Undefined method has_attached_file after Paperclip installation?

Question

Not sure if I've done everything right here. I added the Paperclip gem to my Gemfile and did bundle install. I followed along with the readme instructions on Paperclips Github page.

I wasn't sure if I needed to install ImageMagick. But, I found a script on Github for installation on Snow Leopard, so I ran:

rails plugin install http://github.com/masterkain/ImageMagick-sl.git

But, now I'm getting Undefined method has_attached_file

I'm completely new to Rails and programming. Most of this is pretty advanced for me, but so far I've managed to figure stuff out.
