title: How to install Rails 2.3.2 and 2.3.4 simultaneously on Ubuntu 9.04?
body: <p>I need to install Rails 2.3.2 and Rails 2.3.4 simultaneously on my Ubuntu 9.04 server.  How do I do this?</p>
  
  <p>When I run:</p>
  
  <pre><code>sudo gem install rails
  </code></pre>
  
  <p>...it installs version 2.3.4.  Is there a single command I can use to also install 2.3.2 parallel to the default (latest) version?</p>
  
  <p>Thanks!</p>
