Quite so.

That would be one way to do it but sadly it's not sufficient. On
pre-jaunty Ubuntu systems (and many others), omitting --prefix puts
everything in /usr which is also wrong.
I think the right answer is to provide a way to suppress the --prefix
explicitly. That will provide a workaround to people with the broken
python setup, without making things go wrong for anyone else.
