Comment (by raimue):

 What did you expect as result for the example? Should it be supported on
 `darwin 11` or not? And why would it not be supported on `darwin 10`? I am
 confused by your description.

 Okay, I understand your point now that it should be allowed to add more
 restrictions. This is indeed not possible with my proposal.

 Replying to [comment:32 mojca]:
 > Then again ... if we evaluate dependencies separately anyway, if a port
 includes qt5 PG and that one pulls in dependency on qt5 anyway, the PG
 might not actually need to blacklist any platforms since the platform will
 already be blacklisted by qt5 itself.

 Exactly this is what I was trying to say. We do not need to care about
 dependencies, we only need to specify what *this* port supports.
