To get it working…

ambermeh – Within the script, it has a line starting with “use lib” and a fixed path. In my case that needed to be changed to /usr/lib/nagios/plugins. In the command definition, I also decided to use /usr/bin/perl instead of the built-in Nagios perl. Just by prefixing /usr/bin/perl in command_name. Hope that helps. We’ve got disk, memory, cpu and sessions all working, so let me know if you’re stuck and I can share.
