> An installation of MacPorts and the ports installed by it are only designed to work on a single OS release and a single CPU architecture. If you upgrade to a new OS version (e.g. from Leopard to Snow Leopard) or migrate to a new machine with a different type of CPU (e.g. PowerPC to Intel), you may get lucky and have your ports keep working, but in general, things will break.
> If you are only upgrading Xcode (e.g. 4.1 to 4.2 on Lion) but not the major OS version or CPU architecture, you do not need to reinstall ports as described below.

If you are upgrading from a prior version of Mac OS X, install the latest version of Xcode for your new OS. This will not be done for you automatically; Xcode is not updated by Software Update, so you must update it manually. For Lion, Xcode is available for free on the Mac App Store (after install you may also need to install "Command Line Tools": XCode->Preferences->Downloads; if upgrading from previous version of xcode you may also need to do 'sudo xcode-select -switch /Applications/Xcode.app', [http://stackoverflow.com/questions/9849034/how-to-run-install-xcodebuild see this SO article]). For earlier OS versions, you will find the Xcode installer on the Mac OS X installation DVD or on the Apple Developer web site.

This is not the right place to explain how to install Xcode. We have a section in the Guide on how to do that; this page should just refer users there.
