I want to ask according to Debian policy [1] about a Pre-Depends with
respect to the following build problem of proteus.
To know the proteus version, setup.py imports __init__.py from
subfolder proteus, which itself imports classes depending on python
modules not yet installed.
The problem is already known [2], the upstream bug report is at [3].

[3] https://bugs.tryton.org/issue2705
Should I workaround the problem for wheezy by setting python-dateutils
in Pre-Depends instead of Depends or should I rather wait for the
upstream patch, for which I don't know if and when there will be a solution.
