Bingo! The evil was in:

    PYTHONPATH="/usr/local/lib/python:$PYTHONPATH"

Where PYTHONPATH is empty string, causing the effect

    PYTHONPATH="/usr/local/lib/python:"

Which strangely gets interepreted as if written:

    PYTHONPATH="/usr/local/lib/python:."
                                      |
                                      Current dir

After taking care of this better, the bzr whomped in speed.

Thanks for everybody,
Jari
