(getenv "...") includes too much, it also includes the python libraries
from native-inputs that are only required for tests.  I recommend:

(string-join
  (map (cut (@ (guix build python-build-system) site-packages)
            (list (assoc-ref inputs "this-python-input")
                  (assoc-ref inputs "that-python-input")
                  [...])
            outputs)
  #\:)

(untested).  Possibly there's a simpler way to do this ...

(Many packages simply do (getenv "GUIX_PYTHONPATH"), but that's a bug
in those packages, see e.g. <https://issues.guix.gnu.org/25235>.)

Maxime.
