Comment (by michaelld):

 Ok so i haven't read through the code to see, but if ZMQ allows optional
 use of C++11 then the resulting ABI will be somewhat different for the
 version using C++11 versus the one not using it. That's not idea for
 debugging / tickets, to have to know which version we're working with. It
 would make a lot more sense to either select one or the other and go with
 it for all installs, so that the ABI is consistent across all installs
 (or, as consistent as it reasonable can be).
