[Comment 3 Michał Górny 2017-05-13 07:11:00 UTC]

What's the setuptools version?

[Comment 4 Alessandro Barbieri 2017-05-13 08:36:31 UTC]

At the time of report: 34.0.2-r1 but now I upgraded to setuptools-35.0.2 and this package version 0.4.2-r1 without failures

[Comment 5 Michał Górny 2017-05-15 12:50:59 UTC]

I'll investigate whether it's a bug in this setuptools version or something else.

I'm afraid I can't figure out a way to reproduce this. I've tried with setuptools-34.0.2-r1, with old and new zope-interface, on top of installed, uninstalled, with namespace-zope, without...

I suspect it might be yet another python3.5 namespace issue in pkg_resources. If that is the case, feasible solutions are:

a. upgrading setuptools (as you've done),

b. using the newer ebuilds with fixed namespace support (which are less likely to cause issues).

In either case, I believe the best way forward would be to stabilize both new setuptools and new package versions before marking python3.5 stable.
