Yes, inside the 'run' method within the 'bdist_deb' distutils command I 
had imported setuptools there but not at the top of setup.py.

The patch looks for the option 
'--ignore-single-version-externally-managed' and then accordingly sets 
an env var that is used in the install line.

This looked like a reasonable way to control behavior inside the rules.  
That's why I was asking if that is what you had in mind.

I'll look at the branches and what needed to be added.
