Thanks Johannes, that more or less gets it running.  It gives a warning

--------------------------------------------------------------------------
A deprecated MCA parameter value was specified in the environment or
on the command line.  Deprecated MCA parameters should be avoided;
they may disappear in future releases.

  Deprecated parameter: plm_rsh_agent
--------------------------------------------------------------------------

but otherwise the test runs fine.

There's a suggestion at
 http://lists.alioth.debian.org/pipermail/debian-science-commits/2014-J
anuary/024112.html
that we should use OMPI_MCA_plm_orte_agent instead.  But when I use
that, I get the same test error that I got without the variable.
