htgoebel pushed a commit to branch wip-python-build-system
in repository guix.
commit 0ae5ac7e3aa7d1e4c73929e121887fb48d827e0f
Author: Marius Bakke <address@hidden>

guix: python-build-system: Import setuptools before calling `setup.py'.
This is needed for packages using "distutils" instead of "setuptools" since
the former does not understand the "--single-version-externally-managed"
flag. Also export __file__ since it will be unset when setup.py is called
from
python "exec".
* guix/build/python-build-system.scm (call-setuppy): extend "python
setup.py"
call to import setuptools, export __file__, and call setup.py from
setuptools python environment.
