 I got this error when installing a package but I already have Xcode 3.2.2
 installed.  How does MacPorts check xcode version and what can I do?
 Thanks in advance.

 Please remember to use WikiFormatting and to preview before submitting.

 MacPorts determines your Xcode version by running "`xcodebuild -version`"
 and extracting the displayed Xcode version number. Xcode 3.0 and older did
 not display the Xcode version number here, so in this case MacPorts falls
 back to comparing the displayed internal version number of DevToolsCore
 with a list of known version numbers that correspond to public Xcode
 version releases. See
 [browser:trunk/base/src/macports1.0/macports.tcl?rev=68697#L352 the
 macports::setxcodeinfo procedure]. What does "`xcodebuild -version`" say
 on your system? What happens if you simply install Xcode 3.2.2 again
 (possibly using the Dev Tools uninstall script first)?
