The problem is that the ARPACK on Ubuntu is a bit old and buggy. You
need a newer version somehow. Debian unstable has a newer package, so
perhaps if you do something like add a source line
deb-src http://ftp.ca.debian.org/debian/ sid main non-free contrib
to your /etc/apt/sources.list and then acquire the Debian source and build it
apt-get source libarpack2-dev/sid
sudo apt-get install build-dep libarpack2-dev
cd arpack-3.1.0
dpkg-buildpackage
you can then have a set of newer debs for Ubuntu that you can install
with dpkg -i.
I'm not sure if this is the easiest way. This only matters if you care
a lot about the eigs function, which is what ARPACK is used for.
