My version of octave hasn't been updated in a while, but I am just
using whatever blas octave comes with.  Is ATLAS encumbered such
that it cannot be included in octave as its blas?

That's a good place to start.

Also, since ATLAS works correctly, and is generally better than the
reference implementation and about as fast (or faster) than most
vendor versions, why not just use ATLAS?
