upgrade to Rails3 question


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
