MPI problems

I have recently installed dolfin 0.9.7 woth Dorsal. After solving some CGAL business (thanks Harish) I now bump into MPI issues. Anyone that recognize this?

>>> from dolfin import *

It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  orte_ess_set_name failed
  --> Returned value A system-required executable either could not be found or was not executable by this user (-127) instead of ORTE_SUCCESS
