It's probably just as easy to find packages that went the opposite
way: sqlite3 vs. sqlite2, xfce3 vs. xfce4. Also, when we did upgrade
to qt3 it was after making sure most things worked with it. I don't
know how long we waited to make qt3 the "official" qt package.

Python 3.0 is a mostly backwards incompatible update to python. I
suspect most packages will need tweaks and updates to make them work
The python 3.0 upgrade was never meant to be easy. They wanted to fix
some of the warts in python.
I'm pretty sure there will be a good number of packages that aren't
python 3.0 compatible. That being said, they will be in the longer
I really think that Python 3.0 isn't going to see mainstream support
for a while. The upgrade path that the python community suggests is
getting it working in python 2.6 and then fix it from there.
What will you call the binaries? python and python2?
I'm going with Aaron's suggestion. Don't worry about python 3.0 until
more things support it. Or create a temporary python3 repo to support
software in there (and call the package python3) for people who really
want it. Then the python/python2 split will be gentler.
