title: rails update 3.2.5
body: <p>for our redmine-installation (=>tool for project planing, ticketing etc.)
  we installed ruby on our server, which worked fine ...
  But now we need a rails update (Rails 3.2.3) for a redmine update and 
  so the troubles began:</p>
  
  <p>I did the following:</p>
  
  <p>1.) installing ruby 1.9.3</p>
  
  <pre><code>root@information:~#  rvm install 1.9.3

  Depending on your version of ruby, you may need to install ruby rdoc/ri data:
  
  &lt;= 1.8.6 : unsupported
   = 1.8.7 : gem install rdoc-data; rdoc-data --install
   = 1.9.1 : gem install rdoc-data; rdoc-data --install
  &gt;= 1.9.2 : nothing to do! Yay!

  <p>My problem is, that redmine 2.0.1 had problems with ruby 1.9.3
  and so tried to downgrade ruby by e.g. "rvm uninstall 1.9.3" and tried
  to reinstall ruby 1.8.6...</p>
  
  <p>After all I just upgraded to ruby 1.9.3 but failed to upgrade to rails 3.2.5....</p>
  
  <p>Can you help me here ? </p>
  
  <p>I'm new to ruby. Did I forget installation steps?.
  Thanks in advance for your help?
  Cheers,</p>
