Such a patch would fix compilation, but the fact is this version of
Mongrel2 was not tested with ZeroMQ v4 and greater
and I don't know if we can simply bump its version like that. Maybe we
can but I am not 100% sure.

On another hand, mongrel2 development is becoming active again and
they are trying to prepare a release, so I will try to check there if
they ensure zeromq4 compliance and tested it. I will get back to you
when I can on this subject.
