I had that error for some time and when I finally looked into it,
it turned out an old copy of setuptools was (partly) in place.
This error also caused entry_points in setup.py to fail.

Look in /usr/local/lib/python${VERS}/site-packages for multiple
setuptools-**-egg-info folders.

You might have (for py27)

setuptools-20.0-py2.7.egg-info
setuptools_hg-0.4-py2.7.egg-info
setuptools_scm-1.10.1-py2.7.egg-info

which is ok, but if you have

setuptools-18.7-py2.7.egg-info
setuptools-5.4.1-py2.7.egg-info

then you should delete the setuptools-5.4.1-py2.7.egg-info

Check that the old port is not installed - pkg info -ox setuptools

for me the old version of the egg-info dir was an empty dir left behind
from the old port version and I deleted it manually - no more problem.

Check each python version as it most likely happen to each version
installed at the time the old version was meant to be removed.
