Comment (by aric):
I see that there might also be some others besides CLADIV.

Those LAPACK functions I put there explicitly; they aren't part of
ARPACK. This was the major issue in getting the ARPACK wrappers to
work - those routines (*ahqr) distributed
with OS packages (in Linux anyway) are complied in some way that
they don't work correctly. They do work when complied seperately
so I assume it must be some sort of optimization issue. I never
followed up with the LAPACK maintainers though.
It may work without these files on OSX - that would solve the problem no?
