from http://benwoodall.com/2011/06/rails-global-access-to-rake-dsl-methods-is-deprecated/

So apparently the newest version of Rake (0.9+) breaks rails. You will get the error: WARNING: Global access to Rake DSL methods is deprecated. Please Include ... Rake::DSL into classes and modules which use the Rake DSL methods. The quick fix is to downgrade to Rake 0.8.7, but you can also add this little [...]
