From 46bcdcc287ecfc1db8b7a0429e72517f407b580d Mon Sep 17 00:00:00 2001 From: Marius Bakke Date: Thu, 29 Sep 2016 18:41:35 +0100 Subject: [PATCH] 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.
