I finally activated mercurial on puppy wary 511.
see page

steps are
1. install python 2.6.pet
2. install mercurial 1.0.1 deb of debian lenny
3. download and extract .py files from .tgz, the debian web site
4. set PYTHON_PATH to extracted .py folder
5. copy .so files included in deb to extracted .py folder
done
but I'm not sure it works even when using push command. I just checked with "hg clone"
