The old setup for openmpi was found to cause compiler conflicts in some
cases, since openmpi itself wraps a compiler and the same compiler must be
used to build other libraries in some cases (and it's not really possible
to delineate just those cases).

The simple fix is:

    sudo port upgrade --enforce-variants arpack -gcc45 +openmpi
