Absolutely, and I've made mine more flexible just now so you can say:

cocoa_depends_on :key, :dependency
cocoa_depends_on [ :key1, :key2 ], :dependency
cocoa_depends_on :key, [ :dependency1. :dependency2 ]
cocoa_depends_on [ :key1, :key2 ], [ :dependency1, :dependency2 ]

(I think on reflection cocoa_depends_on is a little more clear than  
cocoa_depends)

Tiger 10.4.2 - haven't tried this on Panther.

I've attached my code. It relies on the property handling stuff in  
CVS HEAD (unless that's been released now ... ?)
