Did you unpack the Cython archive correctly? Is there a Shadow.py in
your src/Cython-0.11.1/Cython/ folder?

Did you follow the 2nd set of instructions & modify both your
PYTHONPATH & PATH env vars? Have you confirmed they're correct? This
is the sort of error I'd expect if those weren't set up properly.

Yes, however none of these happened when I just installed Cython to
the XP, OSX & Ubuntu boxen I'm working on, so this isn't usual
behaviour.

What is your setup? What OS?
