[Numpy-discussion] why doesn't numpy.distutils find ATLAS?

I have installed numpy with my own ATLAS, but trying to install PyMC,
it can't find the ATLAS libs. I also have an older package that
formerly installed but no longer does. I'm being a bit lazy, but am I
missing something? Briefly checking, it looks like the
conventions/assumptions for site.cfg in an installation as per
site.cfg.example are different from those expected of
numpy.distutils.system_info. I have the directories specified under
[DEFAULT] as per the installation instructions. If I don't have the
libraries installed in one of the default folders, it looks like
they're not found.
