Actually, I just noticed the ATLAS packages we ship in F18 are also broken:
libblas.so.3 is missing, so if something links only -lblas, or links -lblas
before -llapack etc., it will get the unoptimized reference BLAS functions!
If you link to -lblas, you're shooting yourself in the leg in the first
place, since that's the reference implementation on current Fedoras. If
you want the ATLAS version of BLAS, you need to link -lf77blas -latlas.
