profile.module required in drupal 5.x

the .info file needs the "dependencies" listed, the file should look like this now:

name = Affiliates
description = "A module that allows affiliate click-throughs to be tracked."
dependencies = profile
package =
version = DRUPAL-5

If profile.module is not enabled you will get some sql errors on the affiliates configuration page:
yoursite.com/admin/settings/affiliates
