That could mean you're not connected to the internet or that computer cannot resolve the gems.rubyforge.org hostname. try the following into a console window: ping gems.rubyforge.org You should get some output like: Pinging gems.rubyforge.org [205.234.109.19] with 32 bytes of data: Reply from 205.234.109.19: bytes=32 time=424ms TTL=54 If not, then there is something wrong with your TCP/IP Configuration.
