There are two problems with adding Python 2.6 to the supported versions.
First, the installation path changed from site-packages to
dist-packages. This means that most Python packages will need two
changes:
* passing --install-layout=deb to setup.py
* fixing paths from site-packages to *-packages (since the path
now depends on the Python version, yay)
This transition should have happened much earlier and was managed very
badly, but well, now it is here and we have to deal with it. I’m in the
process of evaluating the number of affected packages; it’s probably
huge, but can be reduced using the cdbs hack from Ubuntu.
Second, the maintainer stated on IRC he doesn’t want to upload it to
unstable until the packaging helpers are rewritten *again*, with a
proposal that has some advantages but that clearly lose when compared to
the amount of work it implies. Given that so far only Piotr has
volunteered to work on it (the maintainer won’t do it himself), that
leaves us with no reasonable chance to have python2.6 in the squeeze
timeframe unless he is convinced to delay this rewrite.
(Of course, this was not a requirement for uploading it in Ubuntu.)

To put it simply:
* Most packages using cdbs should be safe.
* Some packages using dh (most of those building only one binary
package) should be safe.
* All the rest needs updating, at least for the new setup.py
option.
