Ports build with the standard Xcode gcc compilers unless there is a good reason not to. The reason why many ports have variants to use MacPorts gcc compilers is not because they particularly want to use the MacPorts gcc C or C++ compilers, but because they want to use a Fortran compiler, which Xcode doesn't provide.
