This is the output you're talking about, right?
Looking at the last couple lines, it looks like its trying to use f95, not gfortran. Not sure why that would be since you're using `python setup.py config --fcompiler=gfortran build_ext --inplace`
Have you tried doing `build` instead of `build_ext --inplace`?
