It appears that portmap is not running on the local (client) machine.
Without portmap running on the client, you won't be able to mount an NFS
share. Keep in mind that you can make the portmap daemon listen only on
the loopback interface, by uncommenting the example line in
the /etc/defaults/portmap file.
