If I remember well, I forced using gfortran for FC 7.

Not really, because it is not needed. The problem is that ATLAS is 
basically impossible to build in a reproducible way, so I do not provide 
binary rpm. The idea was that you install RPM for scipy, and then build 
ATLAS from the SRPM on your machine, which can be used as a drop-in by 
scipy (ATLAS is picked up instead of BLAS/LAPACK at runtime).

It is your choice, but using the rpms is way easier. I have not tested 
on CENTOS, what is the difference between FC and CENTOS ? I built those 
rpms, but I do not use those distributions, so I do not necessarily know 
how to do thing the right way.

This will force using gfortran:

python setup.py build --fcompiler=gnu95

But this is taken care of by the scipy RPMS on ashigabou....

The log is incomplete: you should give us a complete log (that is, with 
the build directory deleted first), because otherwise, most info are not 
there.
