There's now a third version of this that I pushed to the
cu/farewell-to-pythonpath branch. It now uses GUIX_PYTHONPATH instead
of GUIX_PYTHONPATH_X_Y, which makes it easier to use in any package
definition (as there's no longer a need to import the (guix build
python-build-system) module for packages not using the Python build
system).
I'll merge it soon if nobody has an objection.
Thanks,
Maxim
