python modules circular dependencies

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Hello Debian Python packages Maintainers,

  From <http://debian.semistable.com/debgraph.out.html>,
there are a number of Python libraries that are packaged in a way
that create circular dependencies:

* denyhosts-common denyhosts-python2.3 denyhosts-python2.4
* python-imaging python-imaging-tk
* python2.3-imaging python2.3-imaging-tk
* python2.4-imaging python2.4-imaging-tk
* python-netcdf python-scientific
* python2.3-biopython python2.3-biopython-martel
* python2.4-biopython python2.4-biopython-martel
* python-albatross-common python2.3-albatross python2.4-albatross
* python-docutils python2.3-docutils python2.4-docutils

Circular dependencies should be avoided because they cause problem
during upgrade between stable releases.

Thanks in advance for looking at them.

Cheers,
