emerging with dev-python/sphinx-1.1.3 && -r1 are effective, because they use python2. From the Changelog;

+sphinx-1.1.3-r2.ebuild:  Unrestrict python 3 and make the tests work.

I went to the extent of emerging the progress version and re-tried.
It fails in identical fashion, so this seems to warrant an upstream notice.
Can't find the missing __dict__.
Perhaps it's premature to declare it supports python3
