libMesh doesn't really support using an MPI configuration that differs
from the configuration in PETSc, so if you want to get MPI working in
libMesh then the first thing to do is get it working in PETSc.  You
might want to try the PETSc mailing list for help, but don't just tell
them "can't install valid mpich", give the detailed error messages
involved.  It's hard enough to help diagnose someone else's computer
problems when you do know what the errors are; it's impossible to help
when you don't.
