and it works for me on nrpe, but it needed root priviliges, so added sudo to the command in nrpe.conf and edited /etc/sudoers

Indeed it works only in command line. To work with nrpe I had to add the line bellow before all "use" lines:

use lib "/usr/lib/nagios/plugins";

This plugin works great commandline but wont work with NRPE.

Out of several plugins for checking whether nfs mounts are working, this is the best I've found. It actually tests whether the mount can be accessed, not just whether mtab or showmount report it as mounted. It does not freeze if the mount becomes unavailable.
