Build fails on osx sierra - on building opencv

cd opencv && nix-shell fails:

Installing opencv-3.2.0 on its own via nix-1.11.13, it fails with a very similar error:

That's strange. It works on my mid-2015 Mac Book Pro running Mac OS Sierra 10.12.4. What's your uname? Mine is:

$ uname -a

Also note that installing haskell-opencv from nixpkgs works for me as well:

What do these commands return for you?

Thanks. So I see you're running a newer version of OS X. I just checked and I have an upgrade to macOS Sierra 10.12.6 pending. Let me just upgrade and see if I run into your problem.

[basvandijk]

I've upgraded nixpkgs and it now builds successfully on my upgraded MBP. Can you try again with the latest master? (The build can take a while since not everything is cached yet).

[luntain]

Something changed, because It was compiling for ages but in the end I got the same error:

Were you able to repro it before you made the change?
