OpenID Authentication using AuthLogic Error

I am trying to implement openid authentication using authlogic. I have installed the open_id_authentication in the process but when I entered

rake open_id_authentication:db:create --trace
I get the following error

(in /Users/felix/login)
rake aborted!
Don't know how to build task 'open_id_authentication:db:create'

Can someone tell what am i doing incorrectly

Thanks

This plugin has been broken for some time. Some reports indicate it can be made to work by using older copies of an underlying plugin found on Github. I played around with it an never could find a combination of plugins/gems to make it work.
