However, my port requires that CC, CXX, CPP, and FC/F77 are all from a gcc variant. For example, it's not possible to compile it using CC=clang and FC=gfortran-mp-4.8. How can I modify it so that all compilers come from the same compiler suite?

No, I didn’t know that.

I tried that but the compilation failed. I don’t exactly why but I’ll have a closer look.
