title: Can't install any gems
body: <p>I have been doing JavaScript and some Erlang for around six months and I haven't done any Rails programming lately. Today on my new PC I went to install Rails but got this error:</p>
  
  <pre>
  gem install rails
  WARNING:  RubyGems 1.2+ index not found for:
          http://gems.rubyforge.org/
  
  RubyGems will revert to legacy indexes degrading performance.
  Bulk updating Gem source index for: htp://gems.rubyforge.org/
  ERROR:  While executing gem ... (Gem::RemoteSourceException)
      Error fetching remote gem cache: SocketError: getaddrinfo: The system cannot
   find the file specified.  (http://gems.rubyforge.org/yaml)
  </pre>
  
  <p>A friend of mine said: "<code>gem -v?</code>" to which I responded "1.3.5". He suggested I update to 1.3.6 but I had the same problem. Then I installed a few gems for testing purposes from <a href="http://gems.github.com/" rel="noreferrer">github</a>.</p>
  
  <p>I don't know if I'm missing a source or something, or if something changed drastically in gems.</p>
  
  <p>Also:</p>
  
  <pre>
  gem sources -a htp://gemcutter.org/
  Error fetching htp://gemcutter.org/:
          SocketError: getaddrinfo: The system cannot find the file specified. (http://gemcutter.org/specs.4.8.gz)
