gems not found

[cswilliams]

Hi,
I just tried to setup my ruby on rails app in litespeed following the EasyRailsWithSuEXEC template. However, I still can't get my app to load. My browser just sits spinning and eventually I get a 503. In the error log it gives the following for every gem that I require, for example:
/Users/chris/cart/config/../vendor/rails/activerecord/lib/../../activesupport/lib/active_support/dependencies.rb:496:in `require': No such file to load -- ferret (MissingSourceFile)
I do a 'gem list' at the command line and they are listed so I know they're not missing. Is this some sort of permissions problem? I'm using Mac OSX by the way.

Thanks for your help,
Chris
