   I am trying to run PVM3.3.4 on 2 SUN4 workstations. When I try to start pvmd
I get the following:
   agate> pvmd3 hostfile &
   [t80040000] ready
   [t80000000] eread() pvmd@topaz: [pvmd pid9143] PVM_ROOT environment variable 
               not set.^J
   [t80000000] slave_exec() expected version
   [t80040000] dm_addhostack() from t80040000 wid 0 not found

I have set the PVM_ROOT variable correctly. I even tried to do an rsh onto the
other machine to make sure that the PVM_ROOT variable is set there, and it was.
I am also curious as to why there is a version mismatch between the two pvmd's.
Does any one have any ideas. I tried hardcoding the PVM_ROOT value into the PVM
source, but I still got the version error message.

I tried starting the console and adding hosts manually, and that seemed to work,
I got no error messages whatsoever. The only problem with doing it this way, is
when I start using larger number of hosts, adding each host manually, and will 
quickly become a pain.

My hostfile looks like:
  agate dx=/users/mentat/pvm3/lib/SUN4/pvmd3 ep=/users/mentat/pvm3/bin/SUN4
  topaz dx=/users/mentat/pvm3/lib/SUN4/pvmd3 ep=/users/mentat/pvm3/bin/SUN4

and PVM_ROOT=/users/mentat/pvm3
    PVM_ARCH=SUN4

Does anyone have any ideas?
