[SciPy-dev] building SciPy for CentOS 5

I built ATLAS from source (using the ashigabou FC 7 SRPMS), using 
gfortran 4.1.2


Is the ashigabou SRPM supposed to provide 'cblas'?

Should I use http://math-atlas.sourceforge.net instead?

How do I specify which fortran compiler is used to build scipy?

I've attached the scipy log file.
