At a guess you used some variation of pip/easy_install/setup.py to 
install mercurial outside the apt-get/dpkg mechanism.

If you have pip installed, what does pip freeze | grep mercurial show?

Also you might want to look in the script that is /usr/bin/hg to see 
what it is pointing at.

I would also look in the Python packages directories(site-packages. 
dist-packages) to see what is there. As someone else mentioned this 
smells of a PYTHONPATH issue, where the 2.6.2 version is being picked up 
before the 3.0 version.
