lintian: Should check dependencies for python packages

[Gregor Hoffleit <gregor@hoffleit.de>]

Package: lintian
Version: 1.20.13
Severity: normal

Lintian should include a check for correct dependencies of Python
extension packages. The rule is like follows:

Any package that installs stuff in /usr/lib/pythonX.Y/site-packages must
have a dependency on:

    python-base >= X.Y, python-base << X.(Y+1)



Thanks,

  Gregor
