Comment (by aric):

 Here is some more detail.  Complex number eigenproblems do not
 work on OSX with veclib.  They do work with a custom compiled ATLAS,LAPACK
 and test fine.

 I am guessing it could be this issue
 http://developer.apple.com/hardwaredrivers/ve/errata.html#fortran_conventions
 and perhaps the FORTRAN code snippets there can be of help.

 The test_arpack.py code has the complex tests commented out.
 Put them back in to see the failure (bus error).
