Exactly which FORTRAN compiler are you using and what --fcompiler setting did
you use? We've made the appropriate settings for gfortran (--fcompiler=gnu95),
but we haven't done anything with g95 (--fcompiler=g95), which is what I assume
you are using here.

I think you may be the first person to try to use g95 on OS X with f2py; at
least, the first to tell us about it. Consequently, we'll need your help in
order to figure out what to do. Presumably, the necessary settings should be
similar to those for gfortran. Please take a look at
numpy/distutils/fcompiler/gnu.py:GnuFCompiler.get_flags_linker_so(). Most
likely, that method can be simply copied over to numpy/distutils/fcompiler/g95.py .

Let us know if that works for you. Thanks.
