This points to some old commit not even in nixpkgs, I don't get what's going on - NixOS/nixpkgs@543c453

@ nixpkgs.nix:4 @
let
  nixpkgsSrc = builtins.fetchTarball {
    url =
-      "https://github.com/NixOS/nixpkgs/archive/3561ed6953f96e2178142b04413d200be94e281d.tar.gz"; # master

+      "https://github.com/NixOS/nixpkgs/archive/543c453c8acd8a691a7bcd355acffa08e2db8a84.tar.gz"; # master

  };

Maybe #53 could help.

AH, it's because master is some ancient tag in nixpkgs. You want url = ... # refs/heads/master

There could certainly be a warning or something for this though!!

(although in the case of nixpkgs, imo these tags should be removed)
