Where is login_generator?


I'm working with the latest version of Ruby on Rails. I'm intrigued
by this "login_generator" extension (http://wiki.rubyonrails.org/rails/
pages/LoginGenerator), but when I try to install it on my FC6 Linux
system, I get this error:

[me@mydomain]~/w/easyrx% gem install login_generator
Bulk updating Gem source index for: http://gems.rubyforge.org
ERROR: While executing gem ... (Gem::GemNotFoundException)
    Could not find login_generator (> 0) in any repository

How do I find it?

Thanks, - Dave
