Another example just happened here:

I'm trying to build guix from git. I use 'guix environment guix', and
get 'configure: error: C preprocessor "/lib/cpp" fails sanity
check'. Anything else I need? I'm trying to follow
https://www.gnu.org/software/guix/manual/html_node/Building-from-Git.html

To be clear, it seems that there are different bugs, with one solution
(--container).  That's why I talk about it in this thread.
