Debian Etch - Mercurial in Eclipse

I'm running a Debian Etch system with eclipse. I installed mercurial plugin (http://www.javaforge.com/project/HGE) for eclipse indigo (latest version I guess). And I installed mercurial via the sudo apt-get command. hg status result in

Mercurial version 0.9.5 is too old for HGE. You can try to install a newer version manually, but perhaps the python version in etch is too old also. In fact, Etch is old, that is the main problem. You best chance, if you don't want to upgrade, is to use Mercurial by command line.
