title: How do gems built for java work? Getting error install torquebox gem
body: <p>I'm clearly missing something here. I'm trying to install the torquebox gems and am running into this error (on a mac):</p>
  
  <pre><code>gem install torquebox-server --pre --source http://torquebox.org/2x/builds/LATEST/gem-repo/    
  
  Could not find a valid gem 'torquebox-server' (&gt;= 0), here is why:
            Found torquebox-server (2.x.incremental.424), but was for platform java
  </code></pre>
  
  <p>I have jruby installed, version 1.6.3. It's in my path. I don't understand the above error. If you need any more info let me know.</p>
