setup.py: fortran doesn't compile properly when multiple fortran compilers are available

[anna-wang]

In Ubuntu

python setup.py build_ext --inplace

gives the following error when both gcc/gfortran and an Intel Fortran compiler are installed:

RuntimeError: module compiled against API version 9 but this version of numpy is 6
/n/home08/annawang/temp/holopy/holopy/scattering/theory/__init__.py:43: UserWarning: 
Could not import scattering.  You will not be able to do scattering
calculations, but the rest of holopy sould remain usable.

This is probably due to your not having properly compiled versions holopy's
fortran bits.

Removing either gcc or the Intel compiler results in the code compiling properly

The new odyssey module system will not let you have both gcc and intel compilers loaded at the same time, which both makes this issue difficult to fix and probably not relevant any more.

I am closing this because it probably won't come up any more, but feel free to reopen if it does.
