Lenica, I've got some Jaunty packages compiled with Boost 1.35 here, but you 
need to resolve your dependencies manually, as they're built with checkinstall 
and don't contain any dependencies. But it still helps a lot to not have to 
build it yourself.

FYI, configuring, building and creation of the package has been accomplished 
with these commands:

/configure --prefix=/usr --disable-docs
make -j 3  # I use a dual core, so I gain some speed though the "-j 3"
sudo checkinstall --pkgname python-visual --pkgversion 5.0rc3 --pkglicense 
"Boost Public License" --maintainer "Guy K. Kloss \<g....@ma...\>"

Here using python-numpy in version 1.2.1-1ubuntu1, which strangely enough 
works with Python 2.6 on Jaunty (1.3 is supposed to be the numpy version that 
works with Python 2.6).

Indeed, never noticed ...

Maybe you need to add another constructor to the C++ code containing integers?
