You have mercurial and hgext in /usr/lib/pymodules/python2.6 which is in
your sys.path (as can be seen in your output). That doesn't make any
sense, python should have found it (it's there!)

My mistake, I meant to say "aptitude reinstall", but, as you guessed, I
confused apt-get and aptitude's flags O:-)

Maybe there was something wrong with the VPS image, then? python-support
not properly installed (or half-installed?)

hmmm, I'm closing the bug, but I'm short of worried that there was
something wrong and we didn't fix it. Oh well, hopefully it was the VPS
image as I (and you) can't reproduce it in a fresh install of squeeze.
Glad that it works for you :)
