I _can_ do it, yeah. We found under testing that it's best to use the
same LAPACK/BLAS provider for any dependencies of Octave as for Octave
itself, so that's going to entail making variants for Octave, arpack-ng,
and qrupdate. It'll probably be best to create a package based on
lapack-3.4.1 that all of these can build against.
I'd like to see a test case, too.
