So the question becomes, if you build against a lower version of ZMQ, is that an error or does it just reduce your capabilities? Can you require a minimum version, and check this at init time?

CZMQ already uses very extensive asserts to catch bad arguments.
Building against a lower version of libzmq is fine. Trying to use
non-existent features is bogus, IMO.
