OK, a fair cop. I just assumed it would be hard to find given it's not 
linked from pythonmac.org.

Hrm. Still doesn't quite address point #2 though. I guess the answer, 
reading between the next lines, is "it doesn't - just use /usr/local" 
:)

Yeah, I guess I have a whole lotta reading to do. I've opened a can of 
worms, and they're looking scary :(

Having said that, last time* I did this, PyObjC didn't exist and I'm 
*pretty* sure it's making my life easier this time, if I can only crack 
this minor issue of getting Zope up and running in a PyObjC-enabled 
Python, and then have it bundled, and ... :)
