Be careful with 4.1, especially the Fortran part was very buggy there.
4.2+ is recommended.

Hard to tell, without config info, but the most probable guess is that
you miscompiled ARPACK. I have the impression that almost nobody does
it right for the first time. The recommended method:

*Don't* follow the advice inside ARPACK's README about compiling
internal LAPACK2 part. Disable it and link against your normal LAPACK
3.x library. After compiling, turn the static (.a) library into a
shared one (.so) (I can give you a script for that if you like).
Install the shared library. Run ldconfig (!). reconfigure octave and rebuild.

In case you already did that, we'll need more info.
