title: Rails requires RubyGems >= 0.9.4. Please install RubyGems
body: <p>I'm deploying to Ubuntu slice on slicehost, using Rails 2.1.0 (from <code>gem</code>)</p>
  
  <p>If I try <code>mongrel_rails</code> start or script/server I get this error:</p>
  
  <pre><code> Rails requires RubyGems &gt;= 0.9.4. Please install RubyGems
  </code></pre>
  
  <p>When I type <code>gem -v</code> I have version <code>1.2.0</code> installed. Any quick tips on what to look at to fix?</p>
