First, see this document:

Versions may be backported if you have time or inclination to follow a
process. New versions can be placed in -backports, but it has to be in
development branch (Lucid) first, for both technical and social

Two commands you may very much appreciate are:

* apt-get source avogadro
* apt-get build-dep avogadro

These will get you the existing source, including debian/ubuntu
specific patches, and install the build dependencies. That may give
you the tools you need to build 1.0. If you get it to work, consider
reporting this to MOTU or the Debian maintainers.

It looks like right now the only attention this package gets in Ubuntu
is fixing build failures.  Which is fine; you should get in contact
with Debian and see if they're working on it. If they are, it could be
possible to get it sync/merged from Debian unstable to Lucid, test it,
then backport to Karmic.  This may take some time, but it's an
unavoidable consequence; 1.0.0 released little over a week ago.
