Error 302 when installing rake gem

i try to install rake on my clean lenny server, i get the following error:

Updating installed gems
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    bad response Found 302 (http://gems.rubyforge.org/latest_specs.4.8)

any advice here? thank you!

The root of the issue is that gems.rubyforge.org is the old gem server. It now redirects to the new one is at rubygems.org.
