title: Error starting mongrel on windows after using RubyInstaller 1.9.1 RC2
body: <p>I installed Ruby via the RubyInstaller 1.9.1 RC2 available from <a href="http://rubyforge.org/frs/?group_id=167&amp;release_id=42563" rel="nofollow noreferrer">rubyforge</a>, updated gems, and installed rails.  Everything worked fine using webrick.  For fun, I installed mongrel using "gem install mongrel".  The installation went fine:</p>
  
  <pre><code>Successfully installed gem_plugin-0.2.3
  Successfully installed cgi_multipart_eof_fix-2.5.0
  Successfully installed mongrel-1.1.5-x86-mingw32
  3 gems installed

  Installing RDoc documentation for mongrel-1.1.5-x86-mingw32...
  </code></pre>
  
  <p>Now, when I start the webserver using "ruby script/server", I get the error:</p>
  
  <p>"The program can't start because msvcrt-ruby18.dll is missing from your computer."</p>
  
  <p>Then, webrick starts and runs normally.</p>
  
  <p>I'm guessing its a issue using Rails 1.9 and mongrel expects 1.8?  (I'm new to rails and there is no real reason for me to use mongrel.. just poking around)</p>
