I'm afraid we were unable to support xgrid after the 1.2 series as no
developer had access to an xgrid server. I recently received a complimentary
copy of OSX-server from Apple, and I expect to restore xgrid support at some
point in the 1.5 series.

It looks like you are hitting some issue with 1.2 relating to a change in
xgrid between OSX versions. I personally won't be going back that far to
deal with xgrid issues, so I would suggest sticking with 10.5 if xgrid
support is required.

Alternatively, you can just use OMPI's rsh support to do the launch. Get an
xgrid allocation (I don't know enough about xgrid yet to tell you all the
details), create a hostfile with that info, and then mpirun -hostfile <file>
-mca plm rsh ...  (assuming you use OMPI 1.4.x).
