Check any .pth files you can find. I suspect mpltoolkits has some magic in it to make the namespace package work on 2.7.

sys.path ['/usr/local/lib/python36.zip', '/home/rosuav/cpython/Lib', '/home/rosuav/cpython/Lib/plat-x86_64-linux-gnu', '/home/rosuav/cpython/build/lib.linux-x86_64-3.6', '/usr/local/lib/python3.6/site-packages']

/usr/local/lib/python36.zip doesn't exist. In /usr/local/lib/python3.6/site-packages are a bunch of things that I've installed using pip, but grepping for '/usr' in the -v output comes up blank. There is, however, one .pth file there:

$ cat /usr/local/lib/python3.6/site-packages/matplotlib-1.5.1-py3.6-nspkg.pth import sys, types, os;p = os.path.join(sys._getframe(1).f_locals['sitedir'], *('mpl_toolkits',));ie = os.path.exists(os.path.join(p,'init.py'));m = not ie and sys.modules.setdefault('mpl_toolkits', types.ModuleType('mpl_toolkits'));mp = (m or []) and m.dict.setdefault('path',[]);(p not in mp) and mp.append(p)

Is it possible that that's the cause? And if so, should "python -I" remove /usr/local/lib/python3.6/site-packages from sys.path?
