Rails - Jul 2009 - 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.
