what do you get when you run the unittests, even travis is failing so we do have some trouble somewhere

[mikecorey]

Test_zactor, test_zbeacon, test_zhelper all passed.

test_pyre failed with the following output:

I should also mention that I made a fresh conda env for those tests (they also failed in the original conda env)

[sphaero]

I'm not familiar with conda but as travis does complete, see here: https://travis-ci.org/zeromq/pyre/jobs/409289899
Can you try without conda?

[sphaero]

I haven't tested OSX in ages. I guess it's also a good idea to add an osx unittest to travis
