--single-version-externally-managed is a setuptools option IIRC.

I've looked at its setup.py and found this:

if arg1 == 'egg_info':
     from ez_setup import use_setuptools
     use_setuptools()
if arg1 == 'bdist_egg':
     from setuptools import setup
else:
     from distutils.core import setup

So it is probably recognized as a setuptools project by pysteup3 (in 
packaging.util) but then uses bare distutils, which doesn't have the 
--single-version-managed option.

Maybe in this case (when the call to setup.py --single--...) fails, we 
can fallback onto bare distutils install on packaging.install ?
