It does not work for me, still cannot find ''.
I am trying to understand the commands that you use to define

    address@hidden ~$ guix build libvdpau-va-gl
    guix build: error: libvdpau-va-gl: unknown package
    address@hidden ~$ guix build vdpauinfo

Where can I find 'pre-inst-env'?  Does this make guix aware of the
libvdpau-va-gl package?

I'm running GuixSD 0.14.0 on real hardware, and did a pull and upgrade
just yesterday.
