I disagree.  I am using PVM 3.2.2, and the command "pvm hostfile"
works just fine for me... it starts up a pvm daemon on each of the
hosts specified in the hostfile, and gives me a pvm console prompt.

A recommendation to the original poster, look for messages in
/tmp/pvml* on both the local and remote hosts.  Also, you may
need to have a .rhost file on each of the hosts that contains
the name of the machine that will be starting up the daemon (
and this file must be world readable, and your home directory
must be world searchable).

Finally, make sure that you have dx= and ep= entries in your hostfile
that tells the local host where the pvm daemon and any executables
"live" on the remote hosts.
