This causes a file/directory collision when packaging is first installed using distutils and then reinstalled using setuptools. ERROR: preinst Installation of a directory is blocked by a file: '/usr/lib64/python3.5/site-packages/packaging-15.3-py3.5.egg-info' This file will be renamed to a different name: '/usr/lib64/python3.5/site-packages/packaging-15.3-py3.5.egg-info.backup.0000' The usual solution to this problem is to hard-depend on setuptools at build time. However, that would create a circular dependency in this case. My suggestion would be to patch setup.py to never use setuptools. Upstream is likely to reject such a patch, so we would probably need to carry it at the distro level.
