For what it's worth, the posted binary seems to work fine on my OS-X 
10.5 PPC system (python2.6), so maybe the PPC part works, the Intel part 
not.

Well, I still think if you do everything right, it works, but yes, it is 
a pain to get right, and a pain to test. Building on the oldest system 
you want to support is a lot easier.

I don't think so -- that's a lot to maintain, and the older versions 
work on the newer OS -- so why build the newer?

Also a lot (OK -- some, I have no idea how many) of us re-distribute, 
via py2app, and so need Universal binaries that work on all the systems 
we need to support.

10.4 or greater would be great -- basically matching the python.org builds.

yup.


Thanks for working in this!
