couldn't find file 'dataTables/jQuery.dataTables'

Hello I'm trying to implement dataTables per the railscast[1] on it. I just want to setup the simple client side version he introduces in the beginning. So far I've added this to my gem file:

group :assets do
  gem 'jquery-datatables-rails', github: 'rweng/jquery-datatables-rails'
  gem 'jquery-ui-rails'
end

I ran bundle install. And then added this to my app/assets/javascripts/application.js:

//= require dataTables/jquery.dataTables

And this to my app/assets/stylesheets/application.css:

*= require dataTables/jQuery.dataTables

When I fire up the development server I get this error:

couldn't find file 'dataTables/jQuery.dataTables'
 (in /Users/ircmullaney/RubyCode/cif/app/assets/stylesheets/application.css:13)

I'm sure I'm missing something simple here, but not sure what it is. Any suggestions?
