[Nix-dev] nixops "No such file or directory" after creation

[Richard Wallace]

Ok, that will work if I can figure one last thing out.  My goal here is to
use nixops to deploy an application into virtualbox for testing locally,
and to EC2 for production.  I was hoping to use nixops without being in a
nix-shell if I could so I could use my already installed virtualbox.

I figured I could still do it, but I would just need to get virtualbox
installed into the shell.  So I tried to start it with that package

$ nix-shell --pure -p nix -p nixops -p virtualbox --show-trace
error: while evaluating the attribute `nativeBuildInputs' of the derivation
`shell' at
/nix/store/pbndpjx0wddm96v9kpiv408ljywccnn8-nixpkgs-14.10pre47363.2e2d3f3/nixpkgs/pkgs/build-support/trivial-builders.nix:10:14:

while evaluating the attribute `buildInputs' at (string):1:49:
undefined variable `virtualbox' at (string):1:81

I can install it to my environment just file, though.  So it seems
something about the virtualbox config and nix-shell just aren't getting
along.  If I could get that resolved, I think I'd be off to the races. :)
