Hope i get your attention before running “gem update --system” on  
win32, as the 0.9.5 version of rubygems caused me some problems

I have done what I could to gather the information and write what  
worked for me:

Rails 2.0, gem install, Windows =\> Mongrel Trouble

Please spread the word for windows users 🙂

Thanks very much for the excellent explanation, but I noticed it too  
late. I am going to be ‘WEBricking’ it for a little bit I think. I  
cross posted your blog link to my thread.

Thanks,
