But why doesn't this show up on py3.x

I think that's a pypi glitch while fetching six. dateutil last release was nov/13
we'd have seen it earlier if it was the case.

we seem to be downloading the whl, which is only for 3.3. apparently?

should download the tar.gz, isn't that odd? (I agree its just changed in the last day which is even more odd)
