Rails rack 1.0 error

I have this error when I try to run script / server:

/opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems.rb:827:in `report_activate_error': RubyGem version error: rack(1.0.0 not ~> 1.0.1) (Gem::LoadError) from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems.rb:261:in `activate' from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems.rb:68:in `gem' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller.rb:34 from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/commands/server.rb:2 from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from script/server:3

This is very annoying because I did:

 Successfully installed rack-1.1.0 1 gem installed Installing ri documentation for rack-1.1.0... Installing RDoc documentation for rack-1.1.0...

But he always talks about a mistake. I have Rails 2.3.5, but I don’t think the error is related to Rails, but it looks more like my server related LOL.

Thanks for the help!

You have installed Rack 1.1.0, the required version is 1.0.x.

 $ gem uninstall rack $ gem install rack -v 1.0.1

the above works, during installation you must specify the version: "-v 1.0.1"

for some reason it will not work otherwise.
