This may be caused by my recent changes in numpy.distutils (r6793 and
r6801). The logic to detect universal gfortran was broken for some
fortran compilers for quite some time - that's why our 0.7.0 binary is
broken for mac os x.

In theory, it should not add universal flag if gfortran does not handle
it,  but I did not test on fink or macport, so it may be broken.

cheers,

David
