Yes it does, because I didn't give you the correct command to run. Sorry
about that. Please run
port dependents zmq22

Actually, this is the old version of zmq, and it has been deactivated
during the update (which means its files are not present in /opt/local).
If zmq was active the line would look like this:
zmq @2.2.0_0 (active) platform='darwin 12' archs='x86_64'
You can run port -v installed zmq22 to see that zmq22 has been activated
instead and is providing the same version you had installed before.
Thus, for any installed ports or software you build locally, there
should be no differences (which was what the whole upgrade process
intended to do).

As I said, if you just leave it like it is right now (with zmq22 active
and zmq deactivated or even uninstalled), you shouldn't notice any

Zmq 3.2 is very recent and not completely compatible. Take care when
upgrading, it might break things.
