This fails during loading:

# Gemfile gem "browsercms", :git=>"git://github.com/browsermedia/browsercms.git" 

The failure is because bcms projects are a combination of Rails app and gem. While this works fine, so long as the gem correctly excludes the config/routes and initializers, with a github dependency like above it will fail.

Solution

Rework gems/modules so that they use the vendor/dummy concept that Crafting Rails applications recommends. Use bundler to create the the gem, then generate a BrowserCMS app under the project. This will likely cut down on the error rate associated with testing gems.
