installation: could not determine kind of name for C.zmq_curve_public

[stevegt]

Getting an installation error from a third-party package; not enough of a gopher yet to immediately be able to troubleshoot or fix this -- anyone have any questions or ideas? Which zmq4 commit was lgo last tested against?

Arg. Okay, missed a prerequisite; I had an old version of libzmq-dev installed. Upgraded to libzmq3-dev and this problem went away. Now hitting #82 because I'm using go 1.12.
