The 'methods' method lists plain Ruby methods. The Objective C  
methods are implemented via the method_missing hook, and therefore  
don't show up like that.

There is an 'objc_methods' method provided by RubyCocoa, but it had a  
bug which was fixed in CVS a couple of days ago. Your version may not  
have this fix yet.

XCode documentation tells me there's no method called 'addItem' on  
NSPopUpButton. There is 'addItemWithTitle' though. Can you try it?
