What the difference between this ^^^^ and clapack-3.2.1.tgz at the same site:
    http://www.netlib.org/clapack/clapack-3.2.1.tgz

(Note: only http://www.netlib.org/clapack/clapack.tgz is listed on the
main page, but both URLs do download the same file. The one without the
version string is of course unusable, in case they bump but we don't.)

s/lapack/liblapack/  to keep a coherent naming scheme.
