If written to be cross-platform, Perl scripts are easily portable. I develop under WinNT and post to Linux and FreeBSD servers regularly. There are a few things to keep in mind when uploading (ASC uploads) but otherwise no problems with the different OSs.

I'd suggest trying to use perl from the command-line just to be sure you have it setup properly. Can you get a response from 'perl -V'? Try to run a perl script via 'perl script.pl' (substitute the name of your script!). Once you've confirmed that perl is installed, then begin to debug whatever tool you are using.

Good luck, William
