I was playing with things trying to get things running. This seemed to be
the only way to make things work.

Nfsend never issued any famous last words. But stepping through the code
made me realize that there a few changes needed to nfsend. The
etc/nfsen.conf file has a $piddir variable. Nfsend does not, but should,
use that variable. Here is a diff delta to get nfsend to use the same pid
directory as the other tools. This is nfsend in 1.3.2.
nm02:/usr/local/nfsen/bin# diff nfsend.old nfsend

I now see nfsend in my process list.
