You may have to limit = yourself to gcc 4.7.x, I haven=E2=80=99t been able to get 4.8 to compile and I = think that the old binutils is too blame. For env you could set CC CXX F77 and FC with the appropriate x86_64-apple-darwin14-{gcc,g++,gfortran}-4.7.3 value. I would be interested in your experience if you decide to go ahead.
