This should be fixed in RubyGems 1.6: http://blog.segment7.net/2011/02/19/rubygems-gem-activation-is-changing I''m sure the RubyGems testers would appreciate all the testing/feedback they can get with this since it''s been a problem for a while (though things like bundler/isolate do a great deal to mitigate the issue). -- Eric Wong
