Note however that the fixed ARPACK has only recently been uploaded to
Debian unstable. The ARPACK packaged in Ubuntu might still be buggy.

If you know how to build Debian packages from source, you can try to
grab the Debian packaging and use it to create a personal backport for
Ubuntu (I'm about to do that for Debian), or if you don't, just forget
the Debian packaging and build ARPACK from source.
