回答1:
Try
gem sources -a http://gems.github.com
and then
gem install watir
回答2:
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.

I found this post useful in setting the http_proxy value and then installing.
How do I update Ruby Gems from behind a Proxy (ISA-NTLM)
Looks like this is an old post - but there was nothing marked as the answer :)
