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.
