Try

gem sources -a http://gems.github.com

and then

gem install watir

One line solution (since I can't vote yet):

gem install watir --source http://gems.github.com

That looks like a proxy problem. Use http_proxy environment variable to setup a tunnel, or download the gems manually from rubygems.
