Bug of PARPACK

There is an undocumented bug in the parallel version of ARPACK (PARPACK). It leads to missing eigenvalues in the computed spectrum. Thanks to Jaques Bloch I learned about it. I do not know if this bug will be resolved at some time since it has been present for a while. Since it might be important for other related studies of eigenvalues of large sparse matrices I have written a small patch for it. In addition to the patch you can find some scritps that I have used for the installation of (P)ARPACK in the file below.
