Perl / Cron / .pl question

I'm trying to get a perl script to run via cron on a Linux server and need some help figuring it out.

I do have the cgi-bin system active on the account and the .pl extension is setup as an alias with the .cgi extension. I've already setup the crontab on the account and this is the command I'm trying to use: /dev/null

The file IS there; I've verified it through FTP.

This is the error I'm getting:
/bin/sh: line 1: No such file or directory

I've also chmod the file to 755.

What obvious thing am I missing?
I would recommend submitting a trouble ticket, it looks like that is trying to run a shell script but I am not the unix tech to know for sure :)
