Comment(by vbraun):
For Sage, or any other code that uses blas/lapack, it really does not
matter if these libraries exist as static or shared form. Of course static
libraries are cruft from the dark ages and shouldn't be used nowadays, but
I digress. As long as either is available, the linker will do the right
thing and hook up the code with blas/lapack.
With this in mind, I changed the spgk-install to just use whatever is in
the SAGE_ATLAS_LIB directory, either static or shared libraries. Fedora
ships dynamic atlas libraries ONLY and Sage compiles fine with
SAGE_ATLAS_LIB=/usr/lib64/atlas. I also removed the part where headers
from SAGE_ATLAS_LIB were symlinked to SAGE_LOCAL_LIB and apparently to no
ill effect. Finally, I'm now also looking into SAGE_ATLAS_LIB/lib for
libraries in order to be backward compatible.
I've updated the atlas spkg (same place), please give it a try :-)
