I would suggest in the home directory of the user pqm runs as.

python2.4 setup.py install --prefix ~

Yes, but I believe it's also a solved problem.  Isn't 'install with
prefix' the way it's typically handled?

Or you can just stick a symlink to bzrlib in the directory where pqm lives.

Alternatively, you can just stick a symlink to bzrlib in an otherwise
empty directory, and stick that in your PYTHONPATH.

If the mainline starts including untenable files, we can simply fix the
mainline.

That looks icky to me.
