Where is login_generator?

Hi,

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 [me@mydomain]~/w/easyrx%

How do I find it?

Thanks, - Dave
