Comment(by nate@…):

 I fixed it:

 (I had already done a complete uninstall of macports debugging so not sure
 if that is part of the solution)

 - did a full uninstall of Xcode: sudo /Developer/Library/uninstall-
 devtools --mode=all
 - deleted my /Developer folder
 - installed Xcode from /Applications/Install Xcode.localized/Install
 Xcode.app/Contents/Resources/Xcode.mpkg (may be able to just run
 /Applications/Install Xcode.localized/Install Xcode.app)
 - installed MacPorts
 - did a selfupdate

 All good now!
