title: Two same file names in Xcode project
body: <p>I'm trying to create a project utilizing both MailChimp and ShareKit code.</p>
  
  <p>I believe I'm dynamically linking to them both by dragging their Xcode project files into my new project, then dragging and dropping the desired groups.</p>
  
  <p>The problem I'm having now is that they both use a file name called SBJSonParser from their JSON libraries.</p>
  
  <p>I'm getting an error that says:
  ld: duplicate symbol _OBJC_CLASS_$_SBJsonParser</p>
  
  <p>I don't want / don't think renaming the files would be sufficient, as there are quite a few more filenames they have in common. Does anyone have ideas on what to do? Thanks</p>
  
  <p>Full error:</p>
