Thank you. how to look version of installed dependency, like qtwebkit? it does not appear in `guix package -I`.

I see qtwebkit is necessary for openshot, ok I let it here.

I have guix 0.16, but I installed it from 0.14 and updated every time. Please, how to check really that ci.guix.info is using? When I run `guix package -u` it download from ci.guix.info, but I think there is more efficient way to check if guix-daemon is using substitute server?
