title: Ruby/Obj-C require command fails
body: <p>I'm currently trying to port <a href="https://github.com/marcel/twurl" rel="nofollow">twurl</a>, a Ruby client for the Twitter API, into a OS X command line application using <a href="http://www.macruby.org/" rel="nofollow">MacRuby</a>. My goal is to "tweet" a NSString, but this turned out harder than expected. At first I was using native cocoa libraries, but I ended up not exactly knowing what to do.</p>
  
  <p>However, twurl is capeable of simply "tweeting" a string and should be called to tweet the string passed to it as argument.</p>
  
  <p>I am aware that this is far away from a good solution, but after 7 days of trying to get any of the native Obj-C libraries to work, I'm really close to tears and this is my last chance of getting close to what I want. If anybody can show me a working command-line solution with native code, please do so. I'd really appreciate that.</p>
  
  <p>However, my concrete problem is that, as soon as I run my project, I get the following error: /Users/User/Library/Developer/Xcode/DerivedData/projectname-.../Build/Products/Debug/project.app/Contents/Resources/rb_main.rb:11:in `': no such file to load -- oauth (LoadError)</p>
