I'm trying to use your app on a linux machine under apache and this is the error I received:

1. RAILS_ENV=production script/about
   /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:263:in `load_missing_constant': uninitialized constant Rails::Info (NameError)

Thank you for any help you can provide!
