I forked and published erlzmq2 library - https://hex.pm/packages/erlzmq - original was unmaintained.
Removed the dependency on Make/rebar - removed the ugly side download of zeromq c src now uses distro dev packages (safer/more reliable).
It’s Travis tested on osx/generic Linux.
Docker verified on arch, Debian and Centos (see verification / Makefile | Dockerfiles).
