1) Because any port that relies on mpi will get a version of mpicc that is
built with clang and has no corresponding fortran compiler.

2) Since clang is the new default with Apple, there is great interest in
the scientific community for building the c part with clang and the
fortran part with gfortran.

3) If you have a port that depends on boost and fortran, then with your
suggestion there will be ABI issues with the C++ libraries.
