Try mpich2, or better still use mpi-defaults (mpi-defaults-dev).
mpi-defaults is a dummy package that pulls in what we deem to be the
most reliable mpi implementation for the architecture, which on those
arches is mpich2 not openmpi.  lam4 is an alternate option, it was
previously the mpi-default but is currently being deprecated in favour
of mpich2.

Hope that helps,
