[macos] ld: symbol(s) not found for architecture x86_64

An error occurred while installing rbczmq (1.7.9), and Bundler cannot
continue.
Make sure that `gem install rbczmq -v '1.7.9' --source 'https://rubygems.org/'`
succeeds before bundling.

seems to be linked to differences between gcc and g++ and/or stdlib c/c++

here is the full log: https://gist.github.com/localhostdotdev/08316de68c5e82c3bf840f8a21b1f00b

also latest versions aren't pushed on rubygems

(oopsie just noticed it was all happening 4 years ago, cool idea to vendor everything BTW)
