Fixing octave, so plot(1) works.

Linking octave with clapack did not work.

I updated lapack, and additionally I build it with atlas, instead of blas. That should give
better performance. I don't know if atlas builds everywhere though.

On the other hand, maybe some programs linking with liblapack will fail. We'll have to check
the hydra reports.

I plan to remove clapack; liblapack provides a C interface too.
