title: Why is reinstalling Ruby 1.8.7 failing
body: <p>I tried to reinstall Ruby 1.8.7 using RVM after having troubles with Homebrew. I reinstalled Homebrew and RVM, and I have Ruby 1.9.3 and 2.0.0 working fine. </p>
  
  <p>One of my projects uses 1.8.7 so when I used:</p>
  
  <pre><code>rvm install 1.8.7
  </code></pre>
  
  <p>I got:</p>
  
  <pre><code>The requested url does not exist(22):'http://production.cf.rubygems.org/rubygems/rubygems-2.0.9.tgz'
  Checking fallback: ftp://production.cf.rubygems.org/rubygems/rubygems-2.0.9.tgz
  Checking fallback: http://www.mirrorservice.org/sites/production.cf.rubygems.org/rubygems/rubygems-2.0.9.tgz
  No fallback URL could be found, try increasing timeout with:
  
  echo "export rvm_max_time_flag=20" &gt;&gt; ~/.rvmrc
  
  There has been an error while trying to fetch rubygems. 
  Halting the installation.
  </code></pre>
  
  <p>I tried to do:</p>
  
  <pre><code>rvm get stable
  rvm get head 
  curl -L get.rvm.io | bash -s stable
  </code></pre>
  
  <p>Which I found on another Stack Overflow question with a similar error, but it's obviously a bit different.</p>
  
  <p>I run:</p>
  
  <ul>
  <li>RVM 1.22.9 (stable)</li>
  <li>Homebrew 0.9.4</li>
  <li>Mac OSX 10.8.4</li>
  </ul>
