[Pyobjc-dev] Build app under 10.5 XCode to run on earlier systems?

[David E. <dav...@gm...>]

If I have a PyObjC application built using XCode with the default
Python installation and default XCode templates under OS X version
10.5 (example: http://www.ics.uci.edu/~eppstein/LaTeX_Unicodifier.dmg.gz,
although I actually care about a more complex app I'm working on that
is not yet ready for public release), the built app does not include
any of the standard Python framework or libraries and will therefore
not run under earlier versions of the OS that did not come with PyObjC
preinstalled. Is there an easy way to convince XCode to make a more
universal application?

A related question: if I want my app to use psyco, it seems easy
enough to add a few lines in main.py attempting to import and run that
module, and doing nothing if the import fails. But that will only give
a speedup on systems in which psyco has already been installed. Is
there an easy way to convince XCode to include psyco within the build?
