Cannot upgrade to Rails 2.0.2 on Mac OS X 10.5.1

It fails on activesupport with:

ERROR: While executing gem ... (OpenURI::HTTPError) 404 Not Found

here is the command:

sudo gem install rails -y --source http://gems.rubyonrails.org

My experience has been that occasional bandwidth outages are fairly
common for gem downloads. Just keep trying until it works.

Will do. Thanks man.
