MacPorts (formerly DarwinPorts) is a software installation/maint  
infrastructure. It uses whatever compiler "gcc" happens to be.  
Generally, this'll be the same as the XCode gcc, unless for some  
reason the user has installed one of the other/newer gcc versions  
available from the port collection.

This doesn't help with the user's original problem, but the  
likelihood that it's not Apple's gcc is small.
