Comment 6 for bug 1254288

I've just discovered that setuptools_bzr is theoretically able to call "bzr" from the operating system, i.e: the command line version. For being able to do that, we just need to remove dependencies from "bzr", i.e: no need at all to compile bzr under Python3.

I'm going to test this scenario soon in a virtualenv built on Python3.3.
If it works as expected, this will allow

      python3 setup.py sdist --formats=zip upload

Let's see what happens.
