It looks like your path is not setup correctly to find the group server.
Hence the message "No such file".   Check that you have PVM_ROOT and
PVM_ARCH setup as needed.  The group server (an executable file named
pvmgs) which is created during the "make" is (typically) put in the directory
	$PVM_ROOT/bin/$PVM_ARCH

Also, check to make sure that pvmgs was created during the make process.

If, however, you are using someone else's pvm, then you can respecify
where to look for files in a hostfile (using the ep option) to pvm.  
For example, suppose pvmgs resides in the directory "mypvmdir" 
on the machine somemachine then you would use a file containing the line

	somemachine ep=mypvmdir:$PVM_ROOT/bin/$PVM_ARCH
on the machine from which you are starting pvm.

Then when starting pvm, execute   
	pvm hostfile
rather than just
	pvm

See the man pages for pvm and pvmd3 for more information.
