I like your approach better.  It also mirror how the configuration() functions
in setup_xxx.py work.  Lets plan on returning dictionaries from now on, and also
fixing the atlas_info module.

Yeah, they went there originally because they were part of the setup process.
Also, they seem useful to other people trying to build modules.  For example,
other developers building modules that use LAPACK can use the atlas_info file.
This makes me think they should all live in a central place so that people know
where to look for them.  scipy_distutils seems as good of a place as any.  I
guess we could make a scipy_distutils.config sub-package directory.  Maybe that
would be better.?

Not very important to me.  I just want them somewhere easily accessible to the
setup_xxx scripts.  I don't think they should be in a sub-package of SciPy
because this presents problems during the install phase of SciPy.

If anyone else has a grand plan (that doesn't include re-writing autoconf in
Python...) lets talk about it.
