[Nix-dev] Nixpkgs evaluation error on Hydra

[Peter Simons]

Hi,

http://hydra.nixos.org/jobset/nixpkgs/trunk#tabs-errors complains

    at `' [nixpkgs = ..., officialRelease = false]:
    undefined variable `licences'

but I can't see what's causing this error. Does anyone have a
suggestion?

Take care,
Peter
