How do I install / use Devise in Rails 2.3.5?

Question

I have tried to install from the v.1.2.oauth branch of Devise on Github, but I still get an error.

How do I install the devise gem on a rails 2.3.5 application? In particular, I want the one that works with omniauth

gem install devise -v "1.2" 
ERROR:  Could not find a valid gem 'devise' (= 1.2) in any repository

 config.gem 'devise', :git => 'http://github.com/plataformatec/devise.git',
                   :branch => 'omniauth'

ERROR:  Error installing devise:
    ERROR: Failed to build gem native extension.

Support for Rails 2.3.x can be found by installing Devise 1.0.x from the v1.0 branch.
