We've had other reports of xcodebuild hanging before; check the issue tracker or mailing list archives. xcodebuild is Apple software, so Apple is the one to whom you should report the problem, since they're the only ones who can fix it.

One cause of problems we've seen before is if your computer's macports user does not have the correct home directory set. Check with "dscl . -read /Users/macports". The correct home directory is /opt/local/var/macports/home.
