3.9 was added to master two days ago[1]. You have to wait for it to
reach the unstable channel and update, of install it from a checkout of
nixpkgs.

Thanks for the info, that helps, oh and I'm running NixOS which I
installed using
16.03 on to a virtual private server and my configuration.nix file is

It seems I don't have 3.9.0 available, how do I get it?

Hi,
You can install llvm with nix-env -iA nixos.llvm nixos.clang (replace nixos by
nixpkgs if you are not using NixOS).
If you want a specific version, you can install llvm_XX and clang_XX as in
nix-env -iA nixos.llvm_34 nixos.clang_34.
For your issue, it arises because you want to install “llvm” which exists in
different versions.
Usually we provide a default one, but it seems currently broken in your channel.
The fix I provide installs the package by its attribute name (-A option), whis
is, by construction, unique.
nix-env is unable to pick the right llvm/clang amongst:
$ nix-env -qaP llvm
nixos.llvm_34 llvm-3.4.2
nixos.llvm_35 llvm-3.5.2
nixos.llvm_36 llvm-3.6.2
nixos.llvm llvm-3.7.1
nixos.llvm_38 llvm-3.8.0
$ nix-env -qaP clang-wrapper
nixos.clangSelf clang-wrapper-3.4.2
nixos.clang_34 clang-wrapper-3.4.2
nixos.clang_35 clang-wrapper-3.5.2
nixos.clang_36 clang-wrapper-3.6.2
nixos.clang clang-wrapper-3.7.1
nixos.clang_38 clang-wrapper-3.8.0

I'm currently on nixos-unstable-small:

nixos https://nixos.org/channels/nixos-unstable-small
What am I doing wrong?
