Comment (by eschnett):
You can define the default gcc with MacPorts: "sudo port select gcc" lists all available versions, and tells you how to change the default. I have set my default to gcc-mp-4.8.
The default gcc is an Apple-specific version of gcc 4.2. This is outdated, doesn't have a good gfortran, and has Apple-specific modifications (and is thus not supported by gcc), and isn't really supported by Apple any more either. If you type "cc" on OS X, then you will find clang, Apple's preferred compiler.
I think the only "correct" solution is to avoid this compiler.
