 I'd like to use mpich2 rather than openmpi for the MPI library.
 I'm mainly using mpich2, and it seems openmpi and mpich2 can not co-exist
 (Ticket #11576). So, It would be nice if I can choose which MPI library to
 use.

 The attached file is what I tried to compile arpack with mpich2.
 Compilation was successful, but I have not tested if arpack works
 properly.

 Note that the location of include files of mpich2 depends on +default_mpi
 variant.
