Anders, he didn't say what OS version he was using. Also, he's on G4,  
so gcc 3.3 is a native compiler, not a cross-compiler.

But, Thomas, if you're running Mac OS X 10.3.9, then you need Xcode  
1.5, which installs gcc 3.3 and that's supposed to be fine for  
MacPorts. If you're on Mac OS X 10.4.10, then you need Xcode 2.4.1  
which installs gcc 4.0, and your gcc_select should be set to use gcc  
4.0, which is the default. Using gcc 3.3 as your system compiler on  
Mac OS X 10.4 is not supported by MacPorts, and I don't recommend it  
for any reason.
