[typo] Latest SVN, error on blog front page

[Trejkaz]

I updated my development copy to the latest copy in subversion a few 
days ago, and now I'm greeted with this on the front page:

> undefined method `caches_action_with_params' for ArticlesController:Class

The definition of this method is definitely present in the file:
vendor/plugins/expiring_action_cache/lib/actionparamcache.rb

And this line is definitely in config/environment.rb:
require_dependency 'actionparamcache'

Was there some update to one of the parts of Rails recently which 
changes the way it searches for dependencies?
