Ok, Last night i printed out the @INC's from a cgi triggered script and from root's command line and found them to be identical. I then searched through the @INC paths and found the Rexec.pm nodule and checked it's permissions. It is world readable. I didn't (yet) check all the directories leading up to that but will as soon as i get a chance to telnet (SSH) into work (the box in question). In the mean time i'll try the whole shebang on the laptop (which has a very similar install of Linux) and see if it works or not. Thanks for the efforts, Dan.
