The gentoo-science group has set up the math library ebuilds to create 
symlinks in /usr/lib, which can be changed to point to different external 
libraries (the blas libraries created by the blas-atlas ebuild are located 
at /usr/lib/blas/atlas/libblas.*). The thinking is that one could easily 
switch from using ATLAS to ACML, for example. site.cfg offers an opportunity 
to override the names of the ATLAS libraries, but I maybe this is misleading:

# For overriding the names of the atlas libraries:
atlas_libs = lapack, blas, cblas, atlas
