Hi!
After upgrading to Rails3 and the latest plugins, two of the plugins: delayed_job and oauth_plugin don't work.
They display a similar problem, I am not able to use methods they provide. In delayed_job's case I can't use Model.delay.method (undefined method) and with oauth_plugin adding oauthenticate in the controller returns undefined method too.
Could I have missed something in the upgrade? delayed_job is added in vendor/plugins and oauth_plugin via Gemfile using their github repository.
