Hey Chris, From the output the problem seems to be with the rbczmq gem <https://github.com/methodmissing/rbczmq/issues/41> not iruby. And you can watch this issue on it’s repo (seems you’re not the only one - opened 3 days ago) … https://github.com/methodmissing/rbczmq/issues/41 <https://github.com/methodmissing/rbczmq/issues/41> Maybe you might have some luck on the Nairuby mailing list ... https://groups.google.com/forum/#!forum/nairuby <https://groups.google.com/forum/#!forum/nairuby> — King’ori Maina (kingori.co <http://kingori.co/>)
