Can't reproduce. Please to troubleshoot more?

[Comment 2 Patrick Lauer 2013-11-26 05:56:07 UTC]

I can reliably trigger it. Possibly related to the set of installed packages?

[Comment 3 Mike Gilbert 2013-11-30 04:06:56 UTC]

+  30 Nov 2013; Mike Gilbert <[e-mail]> cffi-0.7.2.ebuild,
+  cffi-0.8.ebuild:
+  Skip test_integration.py to avoid bugs 486736 and 489870.

Not really fixed, but not quite as broken. If someone else wants to mess with it, feel free.
