[Nix-dev] Unable to install clang/llvm 3.9

[Wink Saville]

As far as I can tell llvm 3.9 is in nixos-unstable-small
(https://goo.gl/3jkeuz) yet I'm not seeing llvm when I do a query:

[wink at vps1:~]$ sudo nix-channel --list

[wink at vps1:~]$ nix-channel --list
nixos-small https://nixos.org/channels/nixos-unstable-small

[wink at vps1:~]$ nix-channel --update
downloading Nix expressions from
‘https://nixos.org/releases/nixos/unstable-small/nixos-17.03pre91378.1781e95//nixexprs.tar.xz’...
downloading ‘https://nixos.org/releases/nixos/unstable-small/nixos-17.03pre91378.1781e95//nixexprs.tar.xz’...
[1984/7708 KiB, 1860.2 KiB/s]
unpacking channels...

[wink at vps1:~]$ nix-env -u

[wink at vps1:~]$ nix-env -qaP llvm
nixos-small.llvm_34  llvm-3.4.2
nixos-small.llvm_35  llvm-3.5.2
nixos-small.llvm_36  llvm-3.6.2
nixos-small.llvm     llvm-3.7.1
nixos-small.llvm_38  llvm-3.8.0

So what have I done wrong or am I incorrect that llvm-3.9.0 is in
nixos-unstable-small?
