After looking at this a little more (and I haven't confirmed this), but
I'm guessing the problem with PVM and bproc is that it checks the
$PVM_RSH to see if it works, in this case bpsh.  But bpsh doesn't take
node id's of the from "n#", it takes just "#", but gethostbyname() wants
"n#".  So I'm guessing we are in a bit of catch 22.  It'd be nice if
bpsh would support the "n#" naming convention.  Cause I can ping names
like "n1" in my cluster just fine, and gethostbyname() returns the
correct information.
