that's because ksh (like sh) expands the PVM_ROOT variable prior to
passing the command line to rsh().  so what the rsh() command actually
sees as its command line parameters is:

rsh remote host /actual/path/to/lib/pvmd

you *must* use single quotes on this command to prevent the environmental 
variable from being evaluated. ie:

       rsh remote host '$PVM_ROOT'/lib/pvmd

and you will see that this does not work.

unless your system admin has added PVM_ROOT to the default 
variables, you MUST use the PVM_DPATH variable, which the PVM 
folkes were kind enough to add for us poor ksh/sh users.

for more information. please, please, *please* read the pvmd man page, 
included in the distribution.
