I'm running the command "gem update --system". I get the following error message. Any help would be appreciated!

I'm running Rails 1.9.2 patch 136 and ruby 3.0.3.

As of 2011-Jan-02, the RubyGems 1.4.0/1.4.1 release does not work with MRI Ruby 1.9. This is documented: see the release post.

Since you are running MRI Ruby 1.9, please join me in waiting for an updated MRI Ruby 1.9 that will support an updated RubyGems 1.4.
