I found a minor, but very frustrating bug in the Red Hat RPM for PVM.  The
package installs a script /usr/bin/pvm, the final line of which is:

  /usr/share/pvm3/lib/LINUX/pvm

This script starts up PVM, but it ignores the hostfile argument that's used
to configure the PVM virtual machine via the command

  pvm hostfile

To fix this, the final line in the pvm start-up script should read:

  /usr/share/pvm3/lib/LINUX/pvm $1

I've noticed a few news-group postings about pvm ignoring the host file in
this release from Red Hat, but I haven't seen any mention of the fix.
