 Ok. Please, provide output of `port provides` for one of the files from
 `/opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6
 /site-packages/six-1.10.0.dist-info` directory.

 It looks like you've installed `six` package (directly or undirectly) via
 `sudo pip/easyinstall` or `sudo python setup.py install`. And now that
 package interferes with MacPorts installation scripts.
