Hello, Thanks for the hints.

I haven't installed mesa explicitly, and it doesn't show up in `guix package -l`, so I think you must be right that it's coming from a propagated input. I still wonder, though, why there are two different builds of mesa appearing. I suspected it might be related to grafting, so I poked around in /gnu/store and found the .drv files that produced these two different copies. They both seem to be the result of a grafting process. If I rebuild my profile with --no-grafts, the mesa used by programs and the one in the profile are the same, so I'll just put this down to some weirdness with grafting. - Mike
