Btw, something with your local mail queue is off, and it''s not
Rubyforge''s (nor Google''s fault).

<snip> yup, all is good when only one version of Rack is installed.
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).
