Problem with RoR Installation on Mac OSX

Hi mates!
I just need your help …

I have tried to install RoR on my IBook G4 by Hivelogic method (http://hivelogic.com/narrative/articles/ruby-rails-mongrel-mysql-osx
)
And i’ve got a trouble when i ready to install Ruby on Rails.

Here is below a captured text from my iBook:

donnyverdian$ sudo gem install rails --include-dependencies
ERROR: While executing gem … (Gem::RemoteFetcher::FetchError)

getaddrinfo: No address associated with nodename(SocketError)

Do you know, guys, the way to fix my problem…?

rgds,

This suggests that the rubyforge archive is offline or otherwise unreachable. Try again in a while, from a different network, etc.
