Engine classes don't auto load in production environment (Rails 2.3.2 + smerf plugin)

Hi all,

I'm trying to use the smerf plugin in a rails app, and I've
encountered something strange. The plugin uses the 2.3 engines
ability to autoload classes under the app folder (e.g. /vendor/plugins/
smerf/app/*), but I get constant missing errors when I try to call
those parts from the production environment. It works fine in
development. Source is here if that helps:


Any advice appreciated.
