Correct way to point to ATLAS/BLAS/LAPACK libraries for numpy build?

Ok this was pretty simple and essentially follows the install guidelines exactly. I suppose this is more of a question on the numberings after shared libs than about numpy or atlas. Anyway, I just had to create some symlinks:

ln -s /usr/lib64/atlas/___.so.3.0 $HOME/local/lib/___.so

Then removed all configs in the site.cfg and updated my .bashrc:

export ATLAS=$HOME/local/lib/libatlas.soexport BLAS=$HOME/local/lib/libptf77blas.soexport LAPACK=$HOME/local/lib/liblapack.so

After running python setup.py install, I'm good:
