For the more general breakage due to PYTHONHOME and PYTHONPATH, yeah, global environment variables are bad, particularly when an OS relies on tools written in (or embedding) Python. That's the reason virtualenv (and 3.3's forthcoming venv) are a preferred alternative - they give you a space to play in that shouldn't break your system Python or apps that embed it.
