So what's the solution? I'm having the same problem.

Never mind, I figured it out:

 group :assets do
-  gem 'sass-rails'
+  gem 'sass-rails', :git => 'git://github.com/rails/sass-rails.git'
   gem 'therubyracer'
-  gem 'coffee-rails'
+  gem 'coffee-rails', :git => 'git://github.com/rails/coffee-rails.git'
   gem 'uglifier'
 end
