Hi there!
Thank you for your suggestion with regard to python-wxpython. I tried to
implement it, along with your remaining comments. I temporarily removed
python-six. I don’t remember anymore what led me to putting it there.
Unfortunately, I cannot test the result, as I’m now getting this kind of
errors:

I wish I could inspect those temporary files
(/tmp/guix-build-grass-7.8.0.drv-0/tmp70mq13s0.h in the example above), but
they dissapear too quickly. I suspected that my build environment had got
broken in the meantime, as the errors persist when I selectively rollback
various combinations of the changes. I cannot fully verify it, as I don’t know
the way to force the Guix daemon to rebuild (recompile) what’s already in the
store. I tried
   guix build --check
, then
   guix build -S --check
— to no avail. But I switched the OS state (GRUB menu on boot + user profile
generation) to the time of my first successful grass build, and building with
changes results in the same errors. Needless to say, I’m at loss now.
