[Python-modules-team] Bug#829631: python-mock: Depends on funcsigs 1 but Debian only has 0.4-2

[Jeremy Bicha]

Package: python-mock
Version: 2.0.0-1

The first line of python-mock's requirements.txt has this line:
funcsigs>=1;python_version<"3.3"

python-mock does depend on funcsigs but the version of funcsigs in
Debian is only 0.4-2.

I think this is making various builds fail in Ubuntu (which synced
python-mock from experimental), such as python-acme (see
https://bugs.debian.org/829285 ) and tryton-server:
