macports does not support XCode 4.3. They suggest using Xcode 4.2 (or 4.1) on Lion: http://www.macports.org/install.php
That could be the issue.
I did see a possible fix here in the comments: http://mandogmachine.com/2012/02/xcode-4-3-breaks-macports/
sudo xcode-select -switch /Applications/Xcode.app sudo ln -s /usr/bin/clang /Applications/Xcode.app/Contents/Developer/usr/bin/clang sudo ln -s /usr/bin/clang++ /Applications/Xcode.app/Contents/Developer/usr/bin/clang++
But I haven't tried it.
