First of all, my environment:

I have created a fresh rails project, created a config/initializers/mailer.rb containing:
ActionMailer::Base.default_url_options[:host] = "localhost:3000"

with the following Gemfile:

# Edit this Gemfile to bundle your application's dependencies.
source 'http://gemcutter.org'

## Bundle edge rails:
gem "rails", :git => "git://github.com/rails/rails.git"

gem "mysql"
gem "warden", "0.9.7"
gem "devise", "1.1.pre4"

I ran 'bundle install' and 'bundle check' says "The Gemfile's dependencies are satisfied". Now, I attempt to install devise:

If you want to use *edge* Rails, you need to use Devise *edge* as well. Devise 1.1.pre4 is meant to be used with Rails 3.0.0.beta gem.

My appoligies. Thanks Jose.

Hey mate, no need to apologize. :) Actually, there is no way you could have guessed it, since there was no information in the README whatsoever. So I just changed it. Please let me know if you have any doubts!

this info just helped me as well. thanks for clarifying Jose!
