"All possible locations" is pretty much impossible. There really isn't 
any choice but for individuals to customize site.cfg for their setup. 
that's why it's called "site".cfg.

I would like to see a pretty good collection of examples, most of them 
commented out, in there, however. i.e.:

## for AMD atlas:
#library_dirs = /usr/lib/atlas/3dnow/
#atlas_libs = lapack, blas

## for Fedora Core 4 sse2 atlas:
#library_dirs = /usr/lib/sse2/
#atlas_libs = lapack, blas

etc, etc.
