Did you build and install the group server (pvmgs) ? ;-)
It may be done by the "g" target of PVM's top Makefile, but it's a member of
the set of default targets, so it should be built.

The group service code tries to spawn the group server by:

                info = pvm_spawn("pvmgs", (char **)0, PvmMppFront,
                                (char *)0, 1, &gstid);

Don't worry about the PvmMppFront parameter, it doesn't matter to you.

To find the problem, you may try to spawn the pvmgs manually from the
PVM console by "spawn -@ pvmgs" with different forms of specifying the
host to run the pvmgs on. See "HELP spawn" in the PVM console.

Hope it helps a bit...
