title: strange inability to require config/boot after upgrading to ruby 1.9.2
body: <p>I upgraded my ruby to 1.9.2 and now when I try to start up a Rails 2.3.5 app with script/server I get this error: </p>
  
  <pre><code>&lt;internal:lib/rubygems/custom_require&gt;:29:in `require': no such file to load -- script/../config/boot (LoadError)
          from &lt;internal:lib/rubygems/custom_require&gt;:29:in `require'
          from script/server:2:in `&lt;main&gt;'
  </code></pre>
  
  <p>But script/server:2 definitely looks correct, and the file config/boot.rb exists in the right place.</p>
