[I can't create tickets since the wordpress/trac merge, so maybe  
someone else can create a ticket.]

New port: arpack.

ARPACK is a collection of Fortran77 subroutines designed to solve  
large scale eigenvalue problems. homepage http://www.caam.rice.edu/ 
software/ARPACK/

The solvers for complex (single and double precision) seem to be  
buggy, based on my limited testing using the example programs that  
come with the ARPACK distribution. I'm not sure whether this is a  
problem with gfortran, an incompatibility between ARPACK and the  
Accelerate framework, or another problem with the way I build ARPACK.

There is an mpi variant, which will install P_ARPACK (the parallel  
eigenvalue solver) as well. This requires a working mpif77 (see my  
previous message).
