Technically an improvement!  The "not enough slots" error is a known OpenMPI
bug-or-feature, depending on who you ask.  As a workaround, could you please
add this near the top of debian/rules?

export OMPI_MCA_rmaps_base_oversubscribe=1

I'm not sure if this will let MdrunUtilityMpiUnitTests pass, but it should at
least get further and to a more informative error.  The "debian/rules
build-openmpi" target skips the very lengthy compilation of everything else.

A more powerful system shouldn't make any difference.
