Rails 3 paperclip install, now get a LoadError

I am very new to Rails, I am running Rails 3 I recently installed ImageMagick via Homebrew and then launched the 'sudo plugin install git: //github.com/thoughtbot/paperclip.git'

I added "gem" rmagick "to my root gemfile.

Immediately after that, I found that the rails commands no longer work (error below). I tried adding "config.gem" rmagick ",: lib =>" RMagick "to my .rb environment, as some other streams suggested, but this returns a different error (undefined local variable or` config 'method for main: Object (NameError )))

Any thoughts?
