There has was an mpqc-openmpi package from 2.3.1-5 on, however, this has
been dropped again in the current mpqc package in favor of just having
one MPI-enabled mpqc binary. I might revisit this again until wheezy
and maybe have on mult-threaded and one MPI-enabled binary, but at least
for now the above MESSAGEGRP setting should work.
