As David Maslen pointed out in http://lists.debian.org/debian-python/2001/debian-python-200109/msg00000.html Debian doesn't have yet python-2.1 in it's distro, although released in June (2.1) and July (2.1.1). Gregor (the python-1.5 and python-2.0 maintainer) has put experimental packages at http://people.debian.org/~flight/python and was asking for help regarding the packaging (20010801). Jérôme Marant answered (20010803), but since this date nothing happened. I intend to do a NMU of python2.1 based on Gregor's experimental packages that can coexist with python1.5 and python2.0. I hope that these packages will find its way to the woody dist and allow the upload of python-2.1 dependent packages to woody. I will do this upload next weekend.
