Not sure how to run a script from the cgi-bin due to access rights.
This is the way I currently do it:
Minute|Hour|DayOfMonth|Month|DayOfWeek
59 11 * lynx -dump http://www.yourdomain.com/jobs/app.php >/dev/null
Where app.php is the name of the file you want to execute. There are other ways to call it if you don't have lynx, however I don't remember them off the top of my head.
Hope this helps...
