OK - well. Things are working for me now. Here's what I did. I installed a fresh version Ubuntu and ran:
sudo apt-get install nfs-common
Whatever client processes are needed started up just fine, and I am able to run mount without issue.
Here's the output:
dlumma@d-linux64-22:~$ sudo apt-get install nfs-common
