Thanks for the suggestion Felix.

Generally though, I'm trying to avoid any dependencies for the build
coordinator agent, since that should help to avoid problems with
portability. Ideally it wouldn't have any dependencies other than the
guix package itself (and the things it requires).

This issue should be fixed in the latest release, and I've been running
that on one of the build machines and it's been working great, so I'm
quite excited :)

Thanks again,

Chris
