undefined method `active_record' with redmine 2.1, ruby 1.9.3

[pafcioooo]

I have running redmine 2.1.3 (latest stable). I follow install instructions for the plugin. When I executed bundle exec rake redmine:plugins:migrate RAILS_ENV=production, it first give me an error about missing simplecov gem, but after I issue bundle install, next execute of bundle exec rake redmine:plugins:migrate RAILS_ENV=production gives a following error:
(in /usr/local/share/redmine-2.1) rake aborted! undefined method active_record' for #Rails::Application::Configuration:0x00000002b7ae10
/var/lib/gems/1.9.1/gems/railties-3.2.9/lib/rails/railtie/configuration.rb:85:in method_missing' (See full trace by running task with --trace)

Well. It seems that only you have the issue. Maybe something wrong with your redmine installation?

Same here after a succesful bundle install:
