`load_missing_constant': uninitialized constant Sass (NameError)

[snoblenet]

I am using the latest versions of SASS, HAML, Compass, Susy and Firesass.

I've added the following to config/environment.rb in my Rails 2.x app:

 <snip>
 Rails::Initializer.run do |config|
 <snip>
 config.gem "haml"
 config.gem "sass"
 Sass::Plugin.options[:debug_info] = true
 <snip>

When I try to start the server at localhost, I get the following error:

  /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:443:in `load_missing_constant': uninitialized constant Sass (NameError)

Sorry, I've just worked out I don't have to go near environment.rb (though the documentation is a bit ambiguous in this regards). I just have to pass debug_info to Sass on-the-fly when telling Compass to compile my stylesheets.

I'm re-opening this as a reminder to myself to fix the documentation.
