I rebuild python packages for Python-3.5 and following notes were displayed in the emerge output: * Messages for package dev-python/zope-interface-4.3.2: * The following *-nspkg.pth files were found installed: * * /usr/lib/python2.7/site-packages/zope.interface-4.3.2-py2.7-nspkg.pth * /usr/lib/python3.5/site-packages/zope.interface-4.3.2-py3.5-nspkg.pth * * The presence of those files may break namespaces in Python 3.5+. Please * read our documentation on reliable handling of namespaces and update * the ebuild accordingly: * * https://wiki.gentoo.org/wiki/Project:Python/Namespace_packages * Messages for package dev-python/ndg-httpsclient-0.4.0: * The following *-nspkg.pth files were found installed: * * /usr/lib/python2.7/site-packages/ndg_httpsclient-0.4.0-py2.7-nspkg.pth * /usr/lib/python3.5/site-packages/ndg_httpsclient-0.4.0-py3.5-nspkg.pth * * The presence of those files may break namespaces in Python 3.5+.

I'm having the exact same issue with ndg_httpsclient (same versions).

I also see this warning for dev-python/configparser-3.5.0.
Current versions of those packages have fixed namespace support.
