And where exactly did you get it from? Does it have x86_64 support?

It looks like we are not passing any architecture flags to gfortran.
The default architecture appears to be i386 for gfortran but is x86_64
for the rest of Python. Your interpreter is starting up in 64-bit mode
and expecting all of its shared libraries to be 64-bit, too, but the
Fortran ones aren't.

Please show us the output of the following the following:

$ gfortran -arch x86_64 -v
