[14:52:50] <mcepl> Hi, when does setuptools (version 40.5.0) use packages from _vendored directory? I have here https://bugzilla.suse.com/show_bug.cgi?id=1177127#c5 (wheels are NOT from the Python tarball, but generated by SUSE) and I just cannot find the path by which setuptools would use setuptools/_vendor/six.
