old problem: unable to bundle

[polka]

in a rails3.1.3 app the installation rails g dresscode:install finishes fine. but if i do a bundle in $dresscode/bundle it will cancel with >>

Bundler could not find compatible versions for gem "rails":
In Gemfile:
dresscode (>= 0) ruby depends on
rails (~> 3.1.0) ruby

dresscode (>= 0) ruby depends on
  rails (3.2.1)

my Gemfile
source "http://rubygems.org"

gem 'dc_contactform', :path => 'dc_addons/dc_contactform'

group :test do
gem 'rspec-rails'
gem 'factory_girl'
gem 'capybara'
gem 'spork'
gem 'shoulda-matchers'

gem 'guard-rspec'
gem 'guard-spork'

gem 'database_cleaner'

gem 'selenium-webdriver'

gem 'capybara-webkit'

end

gemspec
<<EOF

can u reconstruct my issue ??

its essential to bundle to fire up tests directly out of the gem. i think its unacceptable to run acceptance tests ((lol) or others) from a seperate app.

if i use a rails 3.2.x app i got the error>> undefined method mass_assignment_sanitizer= which should be able to neutralize if you comment it out in development.rb. but in my case there is nothing to comment out.

any ideas????

fixed if you dont specify the version number of rails.
inexplicable why the min version greather than wont work
