I suspect that you may have network issues.  You can see which URLs  
RubyGems is trying to fetch with --verbose:

$ gem list --verbose -r rails

*** REMOTE GEMS ***

GET 200 OK: http://gems.rubyforge.org/latest_specs.4.8.gz

This may help you figure out the problem.  I see:

$ curl -I http://gems.rubyforge.org/latest_specs.4.8.gz
HTTP/1.1 200 OK
