Can't get plugin to ever start

I believe my problem is with embedded perl. I will probably rebuild
nagios from source to get rid of it, unless anyone could possibly point
me in the right direction to fix it. In the interim I have the check
script wrapped with a shell script to get it to work.
Thanks,
