Of course. And test I have, and no, it doesn't work:

undefined symbol: dgesdd_

I'm guessing this is a symbol mangling mismatch between what
lapack_lite2 is expecting and what my atlas install used (i.e. too many
or not enough underscores) For what it's worth, I get the same error
with Numeric.

which brings me back to my first question:

Where should I get a good lapack/blas for Fedora core 4?

There are lapack and blas rpms, but there is no indication of whether
they are optimized or not.
