Got it building. Here's the changes https://github.com/ajevans85/nixpkgs/commit/4fe6e2d554ea591bc526d87c13bdad381fe82ddd .

I'll raise a PR at the weekend after I've read https://nixos.org/wiki/Contributing_to_nixpkgs

I've see the res_9_init missing symbol thing before, but haven't had a chance to track down where it should be and why it isn't there. If anyone wants to poke around and answer those questions, I'd appreciate it!

I didn't know how to read the message, I was searching for Undefined symbols for architecture x86_64.

Searching for res_9_init I think it comes from libresolv on Darwin searching around.

I can see libresolv listed in pkgs/os-specific/darwin/apple-source-releases/default.nix, pkgs/os-specific/darwin/apple-source-releases/libresolve/default.nix and pkgs/os-specific/darwin/apple-source-releases/Libsytem/default.nix .

Only just started using nixpkgs so not sure how to pull it in to the Weechat derivation and test etc.
