I THOUGHT pillow built and installed itself in both paths. But from
locates response, only for 2.6 and 2.7. I'll google for it again, and
see if there is a pip3 utility. Humm, but first, need pip3. But its
pip-3.2, not pip3, so its munching its way thru a python3 install of
pillow.
Now it should be there, but again the install bitched about a missing
tkinter, needs Tcl/Tk-8.5 libraries and wheezy only has 8.4. This is
wearing thin...
