Thanks for your quick reply!

It points to $HOME/.guix-profile/bin/guix, and since I have the package
"guix" installed in my profile, that looks OK to me. At the very least I
am used to it: guix has always been in my profile, and has always worked
well that way.

But I do see how this could cause various failures after a guix pull,
because the guix in my profile has to work with the updated stuff the
pull has placed under ~/.config. So perhaps the real mystery is that I
haven't had any trouble before. And I wonder what strategy to adopt to
avoid it - remove guix from my profile? There was a good reason to
install it last year, but I don't remember what it was. If installing
guix into a profile is not a good idea, perhaps the guix package should
disappear or be renamed to something that indicates its true purpose?

BTW, since I updated my profile with the pre-inst-env guix, I now also
have a new guix in my profile and the build failure has disappeared.

Konrad.
