Installed Ruby fine, works fine. Windows, 1.8.6  
Fire up RubyGems to install rails.  
gem install rails  
Various success messages to screen.

Open a command line.  
rails test  
Ton of creates … OK.  
cd test  
ruby script/server

Get a message saying I’m trying to run 1.3.2 and I’ve got 1.3.1 and I  
should run gem update --system

Go to RubyGems and run ‘gem update --system’’  
Am told that 1.3.6 has been installed.  
Back to command line and repeat  
ruby script/server

Whereupon I get these dumped to the screen:

C:/Ruby/lib/ruby/site\_ruby/1.8/rubygems.rb:777:in  
`report_activate_error': RubyG em version error: rack(1.0.0 not ~> 1.0.1) (Gem::LoadError) from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems.rb:211:in`activate’

Can someone please explain (you’re talking to a newbie to Rails, but  
experienced s/w developer) what happened and how I can fix it.  
Thankyou  
Steve
