I'm running Pd-extended and my Pd-l2ork port on 10.7.5.  Both link
to the Carbon system libraries.  Both run.

An update to the Pd-l2ork port:
* figured out how to build tkpath against the Carbon stuff.  It runs 
fine now.
* got some basic libraries compiled and installed to ship with the app.
(zexy, hcs, cyclone, and a few others).
* currently working on an issue with the Shift key "sticking"-- that is, 
if I
do <Shift-RightArrow> to move an object by 10 pixels, when I release
Shift and then do <RightArrow> it continues moving the object by
10 pixels instead of 1 pixel.  Once I fix that it should be usable.

Best,
Jonathan
