Upgrading GTK+ stuff on Kubunu Dapper Drake

[Donn]

Hi,
I haven't the time or bandwidth to install Gutsy. I need Ubuntu and Kubuntu 
for all the libs they each supply, so it means getting another desktop via 
aptitude after the initial install -- a task too horrible to imagine right 
now.

Is there any way I can get the latest gnome2 packages installed on my stale 
old system?

I need GTK+ latest, python-gnome2-desktop and friends -- all that stuff. 
Mainly I want python rsvg which is missing entirely on Dapper.

I have backports enabled, but there ain't no new versions coming along.

I have tried compiling from sources, but I get into weird knots when trying to 
compile the latest GTK+. I will try again, but don't want to break 
Ubuntu-desktop which another user needs (via ssh from a laptop).

I know this is the nature of the beast, it's just that I really hope someone 
will have a recipe.
