Redmine

Hi, this is the first time I've installed Redmine on Windows and I'm having some troubles running rake tasks during the installation:

Bundle installation worked like a charm:

bundle install --without development test rmagick

Bundle complete! 27 Gemfile dependencies, 46 gems now installed.
Gems in the groups development, test and rmagick were not installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

Then comes the token generation...

 bundle exec rake generate_secret_token --trace

It seems that rake cannot load the package actionpack-action_caching, but Bundler installed it as you can see on the package list.
Must I set any environment variable in order to get the packages found?
