Description
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).

The ARPACK needs to be compiled as f77 code, so the `-ff2c' is needed for gfortran. With this small change the test programs that come with ARPACK appear to run correctly.
