The -identifier method you're presumably accessing comes from the
NSUserInterfaceItemIdentification protocol, which is adopted in NSView (and so
inherited by NSButton). That protocol was introduced in 10.7. So, an NSButton
really doesn't have an -identifier method in 10.6.
I suggest that you use the "tag" property, instead. It's already an integer.
