Can someone tell me what I need to do to get dynamic groups to work?
I've tried running several group examples on architectures SUN4, CM5,
and PGON, and the programs always hang.  I've tried this both after
starting pvmgs in the background, and without doing this (the doc file
said the group server is automatically started by the first task issuing
a group command, so I'm not sure what else I should be doing/not doing.)
I ran the included makefiles, so -lgpvm3 is linked in.

For example, when I try the spmd program (which creates group "foo"),
the daemon output is:

[t80040000] [t40020] libpvm [pid5333]: mksocs() connect: Can't assign requested address
[t80040000] [t40020] libpvm [pid5333]: pvm_mytid(): Can't contact local daemon
[t80040000] [t40020] libpvm [pid5333]: pvmgs: Can't contact local daemon

Programs that do not use groups work fine.  Is there anything you have to set
up in your environment beforehand to use this feature?

Any suggestions are appreciated.
