New description:
SAGE_ATLAS_LIB is supposed to allow the use of an external ATLAS
installation rather than have Sage build it. I think if Sage builds ATLAS
once, then you ought to be able to copy the relevant files from that build
to another directory and then use that directory as SAGE_ATLAS_LIB the
next time you build Sage. But this doesn't work on Solaris: on Solaris,
when Sage builds ATLAS, it explicitly deletes the file liblapack.so,
installing liblapack.a instead. But when it tests SAGE_ATLAS_LIB, it
tests for the existence of liblapack.so.
The new spkg just tests for the existence of liblapack.a on Solaris.
The new spkg is here:
