It? I gave you two different options.

Well it's not an arbitrary string, it's the location of the installed
mercurial/ directory. Double-check against 'ls'.
The usual reasons for these sorts of problems are:
- running a different copy/version of the script than you think you are
(multiple installs? '.' in path? check 'which' and PATH)
- inability to find libraries (not in PYTHONPATH)
There's really very little else that can go wrong. You just have to make
sure you've double-checked all your assumptions.
Setting the version works like this:
make runs setup.py
setup.py calls mercurial/version.py to find version
version.py runs 'hg identify' and parses it
version.py creates __version__.py
setup.py copies __version__.py to the library directory
installed hg reads __version__.py
Seems you're getting fouled up in step 3.
(Newer hg takes version.py out of the equation)
