We currently do not build mathplotlib with any backend. This can be very confusing for users. They will try to use matplotlib and it will simply display nothing (see #51337). We should ship at least one backend. `tk` was chosen somewhat arbitrarily. The gtk backend is problematic (see https://github.com/NixOS/nixpkgs/issues/50959#issuecomment-441327767) so tkinter seems like a good choice. There is already a backend provided on darwin so there is no reason to include tk there.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.09
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
