Jari,

Your python-based packages listed below all collide with each other and
python2-setuptools by shipping parts of the latter.  They also bundle
other python libraries instead of shipping them separately.

* pylint: bundles astroid (the successor to logilab-astng)
* python-logilab-common
* python-logilab-astng (obsolete)
* python-paramiko: bundles ecdsa
* spambayes: bundles lockfile, pydns

Furthermore, the non-program modules should be built for both python2
and python3; cygport's python-wheel will do this for you.  The programs
should use whichever of python{2,3}-distutils for the Python version
they require.
