FreeCAD does not build on unstable

Issue description

FreeCAD does not build on https://hydra.nixos.org/job/nixos/trunk-combined/nixpkgs.freecad.x86_64-linux

Steps to reproduce

Hydra does them, otherwise .. nix-env -iA freecad

Technical details

(probably not needed)

• system: "x86_64-linux"
• host os: Linux 4.17.4, NixOS, 18.09.git.58373c8 (Jellyfish)
• multi-user?: yes
• sandbox: yes
• version: nix-env (Nix) 2.0.4
• channels(matejc): "nixos-17.03pre98682.f673243"
• channels(root): "nixos-17.03pre98682.f673243"
• nixpkgs: /home/matejc/workarea/nixpkgs

Problem

Boost is not build with python anymore.

Solution

let
  boostWithPython = boost.override { enablePython = true; };
.
.
.
in

and then use boostWithPython instead of the boost in the buildInputs

Someone can use this for making PR, or wait for me until I get bored watching FreeCAD compile every time I upgrade the channel, which might be soon because it takes a long time to compile :)
