Gem files will remain installed in /home/kenneth/.rvm/gems/ruby-1.9.3-p0/gems/zmq-2.1.4 for inspection.
Results logged to /home/kenneth/.rvm/gems/ruby-1.9.3-p0/gems/zmq-2.1.4/./gem_make.out
An error occured while installing zmq (2.1.4), and Bundler cannot continue.
Make sure that `gem install zmq -v '2.1.4'` succeeds before bundling.

Has this issue been resolved or does anyone know of workarounds for this problem. I'm having the same problem and not sure how to proceed.

Yes, make sure you're not using the 3.x beta version of zeromq -- you wanna use the official 2.x lib.

With a stable 3.x release, will the C extension be updated?
