[LRUG] Rails 2.2 Haml filter problem - production only

[Tom Ward]

Just a stab in the dark, but it might have something to do with class
pre-loading (http://github.com/rails/rails/commit/3bd34b6ffe017dd81fd26743aab052fc4324eb0f).

You could try requiring your smarty_pants file at the start of your
environment.rb rather than the end and see if that helps.
