Would anyone be able to give me a hint on how to get the following
objective-c code working with macruby. The code uses spotlight to
extract metadata from a file.

MDItemRef inspectedRef =
CFArrayRef attributeNames = MDItemCopyAttributeNames(inspectedRef);
NSLog(@"%@", (NSArray*)attributeNames);

I was hoping that including the 'CoreServices' framework would work, but
no joy.

>> framework 'CoreServices'
=> true
>> item = MDItemCreate(KCFAllocatorDefault, '/Users/alan/Desktop/test.jpg')
NameError: uninitialized constant KCFAllocatorDefault
	from core:in `const_missing:'
	from (irb):2:in `<main>'
	from core:in `eval:'
	from core:in `evaluate:'
