I always try to run the latest version of ruby, via chruby and ruby-build.
Recently I ran into a wierd issue, and I’m not really sure how to resolve it,
yet, but managed to work around it. When installing gems with native extensions
via bundler, ruby seems to not find libraries installed via homebrew, it works
fine just running gem install so. Also all extensions installed
seem to stop working between ruby 2.1.0 and 2.1.1. Even though I don’t know
what’s going on, the work around seems to be installing all gems which have
native extensions via gem install GEM and running bundle
after the fact. Now everything works again…
