zerorpc error with pyzmq

[Jon Lederman]

When I run zerorpc, I get:   File "/usr/local/bin/zerorpc", line 5, in <module>

    from pkg_resources import load_entry_point

  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 2749, in <module>

    working_set = WorkingSet._build_master()

  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 446, in _build_master

    return cls._build_from_requirements(__requires__)

  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 459, in _build_from_requirements

    dists = ws.resolve(reqs, Environment())

  File "/Library/Python/2.7/site-packages/pkg_resources.py", line 628, in resolve

    raise DistributionNotFound(req)

pkg_resources.DistributionNotFound: pyzmq==13.1.0

Is there a way to run zerorpc with a newer version (14+) of pyzmq.  How to handle this?
