Hi,

I tried a gem update today and among many of the problems was that rack was updated to 1.1.0 and caused Rails apps to fail with the following error:
RuntimeError: RubyGem version error: rack(0.9.1 not ~> 1.0.1)

I really don't think most people are going to understand the very particular definition of "~>" that RubyGems uses. I had to go off and search through the RubyGems guides to find any references to it. Perhaps the message could be replaced with an appropriate phrase?

Although I guess the ideal behaviour would be to satisfy the ActionPack dependencies?

gem --version = 1.3.5

Regards,
Andrew

   It's explained well in http://docs.rubygems.org/read/chapter/7 as RubyGems' rational versioning policy.

   If you can come up with an appropriate phrase, please file a bug in the rubygems tracker.
