: There are several things  you need to check.
:    1).  you can execute a remote shell (rsh) on the machine cabbage.
:         PVM starts remote daemons by doing an rsh or rexec
:    2).  PVM_ROOT is defined in your .cshrc on cabbage
:    3).  Try installing PVM for yourself.  put it in ~/pvm3.  If you have
:         a network of SUN4's then you should have no problem compiling.
:    4)   Make sure that your networked machines have their own /tmp
:         directories.  If they do NOT, then you need to recompile 
:          all of PVM with -DSHARED_TMP (or something close to that, look
:         at the pvm top-level makefile
:    5)   Make sure that /tmp/pvmd.*,  where * is your user id, does NOT
:         exist before trying to spawn a new pvmd. This is a lock file to
:         keep the same user form spawning to PVMD's on the same machine.

	One point I wanna add as I encountered this problem before:

	You should check if there is any I/O in your .cshrc file, 
	such as "echo ..."

Hope this help!
