and that is my Gemfile

source 'https://rubygems.org'
gem 'rails', '2.3.5'
gem 'rake','0.8.7'
gem 'sqlite3'
gem 'simple_form'
gem 'devise'

# bundler requires these gems in all environments
# gem 'nokogiri', '1.4.2'
# gem 'geokit'

group :development do
  # bundler requires these gems in development
  # gem 'rails-footnotes'
end

group :test do
  # bundler requires these gems while running tests
  # gem 'rspec'
  # gem 'faker'
end

You probably need to change your devise version, since this fetches from the master branch.

Try:

gem 'devise', '1.0.7'
