migrating from login_engine to AAA

I'm in the process of upgrading a rails app from login_engine to acts
as authenticated. I believe that the user table from login_engine is
compatible with AAA. I am having one problem though. When I go to run
the AAA generator I get the following error:

bash-# script/generate authenticated --svn user account

./script/../config/../vendor/plugins/engines/lib/engines.rb:355:in
`initialize': Cannot find the engine 'login' in either /vendor/plugins/
login, /vendor/plugins/login_engine or /vendor/plugins/login_bundle.

I have already un-installed the login engine with the following
command:

bash-# script/plugin remove login_engine

However, it looks like the generator authenticated is still confused.
I'm looking for a solution to this problem but haven't found one yet.

I completely removed and re-installed acts as authenticated and now
I'm getting the following error:

bash-# script/generate authenticated --svn user account
