Then it has wrong dependencies, python3-futures do not make sense as it was
just backport of python3 functionality to python2:

See also:
https://pypi.python.org/pypi/futures - "Programming Language :: Python :: 2 ::
Only"

I would suggest to assign this to maintainers of affected packages -
dependencies need to be resolved there, or python3 itself could provide this.
