I think that copyright only applies to how it is redistributed, and  
not how it is used. Mac OS X LilyPond has a gs in its distribution. So  
its GPL version will apply to that part when (re-)distribution. So you  
need to make sure that when you distribute it, you do not violate any  
of its terms, like tivoization - which isn't an issue on Mac OS X.
