Comment (by merijn@…):

 Replying to [comment:8 and.damore@…]:
 > Is there a reason for going with RC rather than a stable version like
 MacPort's policy?

 RC1 (and now RC2) are the versions recommended by upstream for developing
 for 3.x, since no existing ports depend on 3.x this seems the best way to
 go. Although I guess zmq could be replaced with zmq-devel if that's a big
 issue.
 Similarly #36662 makes sense for zmq, it's just that RC2 was released
 after I submitted the original update ticket for ZMQ.
