Scripts *usually* go to sys.prefix/bin (or sys.prefix/Scripts or site.USER_BASE/Scripts). Are their packages that actually put them elsewhere?

This seems like a possible case. Does this only happen with Linux specific packages (eg: GNOME apps)?

PyPM is an ActivePython tool which installs itself into, say, /opt/ActivePython-2.6 - a single root directory. So we never had to worry about other layouts. PyPM supports virtualenvs too, so "pypm -E /tmp/myenv install lxml" would install into the specified virtualenv.

In ActivePython, sys.exec_prefix == sys.prefix.
