gem remote install or update fails

I cannot get any gem command that involves: 'Bulk updating Gem source index for: http://gems.rubyforge.org/’ to work. I just want to install Rails. Should be simple. I am not behind a proxy. I've tried the 'no- http-proxy' option. I've searched this problem through thousands of posts. I've tries different ruby versions (182,184 and lateset 186). I running windows XP. Immensely frustrated.

Error I get is: gem install rails --v 1.2.3 --source=http://gems.rubyforge.org/ Bulk updating Gem source index for: http://gems.rubyforge.org/ ERROR: While executing gem ... (RuntimeError)     Non-HTTP proxy URI: 4001

  OR if I do not use 'no-http-proxy':

C:\Documents and Settings\Hans>gem update Updating installed gems... Bulk updating Gem source index for: http://gems.rubyforge.org ERROR: While executing gem ... (URI::InvalidURIError)     bad URI(is not URI?): ://:

Rails and rubygems have moved to github. I am also experiencing problems in updating my gems

That's the error message I got when trying to update Thin:

sudo gem update thin Updating installed gems Bulk updating Gem source index for: http://gems.rubyforge.org/ Updating metadata for 300 gems from http://gems.github.com/ ...............................Failed to download spec saucytiger-LivePipe UI-0.9.1 from http://gems.github.com/:         bad URI(is not URI?): quick/saucytiger-LivePipe UI-0.9.1.gemspec.rz .................................................................................................................................................Failed to download spec fatjam-acts_as_revisable-0.7 from http://gems.github.com/:         Gem::RemoteFetcher::FetchError: bad response Not Found 404 reading http://gems.github.com/quick/fatjam-acts_as_revisable-0.7.gemspec.rz .Failed to download spec matta-sdruby-raffle-0.0.1 from http://gems.github.com/:         Gem::RemoteFetcher::FetchError: bad response Not Found 404 reading http://gems.github.com/quick/matta-sdruby-raffle-0.0.1.gemspec.rz More blabla....

I think I have missed something in the Rails bubble.
