    <h2 class="hdr">Installing MacPorts</h2>

    <p>MacPorts version <?php print $macports_version_latest; ?> is available in various formats for download and installation (note, if you are upgrading your Mac OS X to a new major release, see the <a href="https://trac.macports.org/wiki/Migration">migration info page</a>):
    </p>

    <p>Note for Lion users: There is no official release supporting Mac OS X 10.7 yet, but you can test the
    <a href="<?php print $downloads; ?>testing/">MacPorts 2.0.0 release candidate</a> if you like.</p>

    <ul>
        <li>&#8220;dmg&#8221; disk images for <a href="<?php print $snowleopard_dmg; ?>">Snow Leopard</a>, <a
        href="<?php print $leopard_dmg; ?>">Leopard</a> and <a href="<?php print $tiger_dmg; ?>">Tiger
        </a> as a legacy platform, containing pkg installers for use with the Mac OS X Installer. By far the simplest installation
        procedure that most users should <a href="#pkg">follow</a> after meeting the requirements listed <a href="#requirements">
        below</a>.</li>
        <li>In <a href="#source">source form</a> as either a <a href="<?php print $bz2_tarball ?>">tar.bz2</a> package or a
        <a href="<?php print $gz_tarball; ?>">tar.gz</a> one for manual compilation, if you intend to customize your installation
        in any way.</li>
        <li><a href="#svn">SVN checkout</a> of the unpackaged sources, if you wish to follow MacPorts development.</li>
        <li>The <a href="#selfupdate">selfupdate</a> target of the <kbd>port(1)</kbd> command, for users who already have
        MacPorts installed and wish to upgrade to a newer release.</li>
    </ul>

    <p>Checksums for our packaged <a href="<?php print $downloads; ?>">downloads</a> are contained in the corresponding <a

    <div id="requirements">

        <p>Please note that in order to install and run MacPorts on Mac OS X, your system must have installations of the following
        components:</p>

        <ol>
            <li>Apple's <a href="http://developer.apple.com/tools/xcode/">Xcode</a> Developer Tools (version 3.2 or later for Snow Leopard,
            3.1 or later for
            Leopard, or 2.4.1 or later for Tiger), found at the <a href="http://connect.apple.com/">Apple Developer Connection</a>
            site or on your Mac OS X installation CDs/DVD. Using the latest available version that will run on your OS is highly recommended.
            Ensure that the optional components for command line development are installed
            ("Unix Development" in the Xcode 3.x installer).</li>
            <li>The X11 windowing environment (A.K.A. &#8220;X11 User&#8221;)
            for ports that depend on the functionality it provides to run.
                <ul>
                    <li>The &#8220;X11 User&#8221; package is an optional installation on your system CDs/DVD for
                    Tiger, enabled through the &#8220;Customize&#8221; button of the installer, whereas it is included by default
                    on Leopard and Snow Leopard.</li>
                    <li>You can use the xorg-server port instead of Apple's X11.app if you wish.</li>
                </ul>
            </li>
        </ol>

    </div>


    <h3 class="subhdr" id="pkg">Mac OS X Package (.pkg) Installer</h3>

    <p>The easiest way to install MacPorts on a Mac OS X system is by downloading the dmg for <a href="<?php print $snowleopard_dmg;
    ?>">Snow Leopard</a>, <a href="<?php print $leopard_dmg; ?>">Leopard</a> or <a href="<?php print $tiger_dmg;
    ?>">Tiger</a> and running the system's Installer by double-clicking on the pkg contained therein,
    following the on-screen instructions until completion.</p>

    <p>This procedure will place a fully-functional and default MacPorts installation on your host system, ready for usage.
    If needed your shell configuration files will be <a href="<?php print $guide_url . '#installing.shell'; ?>">adapted by
    the installer</a> to include the necessary settings to run MacPorts and the programs it installs, but you may need to
    open a new shell for these changes to take effect.</p>

    <p>The MacPorts &#8220;<kbd>selfupdate</kbd>&#8221; command will also be run for you by the installer to ensure you have our
    latest available release and the latest revisions to the &#8220;Portfiles&#8221; that contain the instructions employed
    in the building and installation of ports. After installation is done, it is recommended that you run this step manually
    on a regular basis to to keep your MacPorts system always current:</p>
    
    <pre>sudo port -v selfupdate</pre>

    <p>At this point you should be ready to enjoy MacPorts!</p>

    <p>Type &#8220;<kbd>man port</kbd>&#8221; at the command line prompt and/or browse over to our <a href="<?php print
    $guide_url; ?>">Guide</a> to find out more information about using MacPorts. <a href="#help">Help</a> is also available.
    </p>


    <h3 class="subhdr" id="source">Source Installation</h3>

    <p>If on the other hand you decide to install MacPorts from source, there are still a couple of things you will need to do
    after downloading the tarball before you can start installing ports, namely compiling and installing MacPorts itself:</p>


    <ol>
        <li>&#8220;<kbd>cd</kbd>&#8221; into the directory where you downloaded the package and run &#8220;<kbd>tar xjvf
        <a href="<?php print $bz2_tarball; ?>">MacPorts-<?php print $macports_version_latest; ?>.tar.bz2</a></kbd>&#8221; or
        &#8220;<kbd>tar xzvf <a href="<?php print $gz_tarball; ?>">MacPorts-<?php print $macports_version_latest; ?>.tar.gz</a></kbd>&#8221;,
        depending on whether you downloaded the bz2 tarball or the gz one, respectively.</li>
        <li>Build and install the recently unpacked sources:
            <ul>
                <li><kbd>cd MacPorts-<?php print $macports_version_latest; ?></kbd></li>
                <li><kbd>./configure &amp;&amp; make &amp;&amp; sudo make install</kbd></li>
            </ul>
            Optionally:
            <ul>
                <li><kbd>cd ../</kbd></li>
                <li><kbd>rm -rf MacPorts-<?php print $macports_version_latest; ?>*</kbd></li>
            </ul>
            
        </li>
    </ol>

    <p>These steps need to be perfomed from an administrator account, for which &#8220;<kbd>sudo</kbd>&#8221; will ask the
    password upon installation. This procedure will install a pristine MacPorts system and, if the optional steps are taken,
    remove the as of now unnecessary MacPorts-<?php print $macports_version_latest; ?> source directory and corresponding tarball.</p>

    <p>To customize your installation you should read the output of &#8220;<kbd>./configure --help | more</kbd>&#8221; and
    pass the appropriate options for the settings you wish to tweak to the configuration script in the steps detailed above.</p>
	
    <p>You will need to manually adapt your shell's environment to work with MacPorts and your chosen installation <kbd>
    prefix</kbd> (the value passed to <kbd>configure</kbd>'s <kbd>--prefix</kbd> flag, defaulting to <kbd>/opt/local</kbd>):
    </p>

    <ul>
        <li><kbd>Add ${prefix}/bin</kbd> and <kbd>${prefix}/sbin</kbd> to the start of your <kbd>PATH</kbd> environment variable
        so that MacPorts-installed programs take precedence over system-provided programs of the same name.</li>
        <li>If a standard <kbd>MANPATH</kbd> environment variable already exists (that is, one that doesn't contain any empty
        components), add the <kbd>${prefix}/share/man</kbd> path to it so that MacPorts-installed man pages are found by your
        shell.</li>
        <li>For Tiger and earlier only, add an appropriate X11 <kbd>DISPLAY</kbd> environment variable to run X11-dependent
        programs, as Leopard takes care of this requirement on its own.</li>
    </ul>

    <p>Lastly, you need to synchronize your installation with the MacPorts rsync server:</p>

    <pre>sudo port -v selfupdate</pre>

    <p>Upon completion MacPorts will be ready to install ports!</p>

    <p>It is recommended to run the above command on a regular basis to keep your installation current. Type &#8220;<kbd>man
    port</kbd>&#8221; at the command line prompt and/or browse over to our <a href="<?php print $guide_url; ?>">Guide</a> to
    find out more information about using MacPorts. <a href="#help">Help</a> is also available.</p>


    <h3 class="subhdr" id="svn">SVN Sources</h3>

    <p>If you are developer or a user with a taste for the bleeding edge and wish for the latest changes and feature additions,
    you may acquire the MacPorts sources through subversion. See the Guide section on <a href="<?php print $guide_url; ?>#installing.macports.subversion">installing from subversion</a>.</p>

    <p>Purpose-specific branches are also available at the <kbd><?php print $svn_url . 'branches'; ?></kbd> url.</p>

    <p>Alternatively, if you'd simply like to view the SVN repository without checking it out, you can do so via the <a
    href="<?php print $trac_url . 'browser'; ?>">Trac source browser</a>.</p>
    
    
    <h3 class="subhdr" id="selfupdate">Selfupdate</h3>

    <p>If you already have MacPorts installed and have no restrictions to use the rsync networking protocol (tcp port 873 by
    default), the easiest way to upgrade to our latest available release, <b><?php print $macports_version_latest; ?></b>, is
    by using the <kbd>selfupdate</kbd> target of the <kbd>port(1)</kbd> command. This will both update your ports tree (by
    performing a <kbd>sync</kbd> operation) and rebuild your current installation if it's outdated, preserving your customizations,
    if any.</p>
    

    <h3 class="subhdr" id="other">Other Platforms</h3>

    <p>Running on platforms other than Mac OS X is not the main focus of The MacPorts Project, so remaining cross-platform is
    not an actively-pursued development goal. Nevertheless, it is not an actively-discouraged goal either and as a result some
    experimental support does exist for other POSIX-compliant platforms such as *BSD and GNU/Linux.</p>

    <p>The full list of requirements to run MacPorts on these other platforms is as follows (we assume you have the basics such
    as GCC and X11):</p>

    <ul>
        <li><a href="http://www.tcl.tk/">Tcl</a> (8.4 or 8.5), with threads.</li>
        <li><b>mtree</b> for directory hierarchy.</li>
        <li><a href="http://rsync.samba.org/">rsync</a> for syncing the ports.</li>
        <li><a href="http://curl.haxx.se/">cURL</a> for downloading distfiles.</li>
        <li><a href="http://martin.hinner.info/libmd/">libmd</a> for checksums.</li>
        <li><a href="http://www.sqlite.org/">SQLite</a> for the port registry.</li>
        <li><a href="http://gnustep.org/">GNUstep</a> (Base), for Foundation (optional, can be disabled via configure args).</li>
        <li><a href="http://www.openssl.org/">OpenSSL</a> for signature verification (currently trunk only).</li>
    </ul>

    <p>Normally you must install from <a href="#source">source</a> or from an <a href="#svn">SVN checkout</a> to run MacPorts
    on any of these platforms. Experimental packaging is available for the FreeBSD (.tbz package), Fedora (.rpm package) and
    Ubuntu (.deb package) operating systems.</p>
