On OSX (10.12.6) I have the following error :

Why is it installing ruby packages in the middle of compilation? How are you installing the package?

That will be really hard for me to diagnose, as the problem is either nix or OSX specific, which I do not use. However, it seems like the problem is related to the fsnotify dependency, which seems to have open issues for OSX. Is nix using the latest version of fsnotify?
