Summary: "-framework Python" for building modules is bad

Initial Comment:
We should use the -bundle_loader method for linking 
modules for both the framework and non-framework 
verisons of Python.

All of these "version mismatch" errors would pretty much be 
avoided if this were the case, since a 10.2 and 10.3 
MacPython 2.3 should be binary compatible.  There are other 
reasons to use -bundle_loader, such as using the same suite 
of modules for both Stackless and regular Python.  Besides, 
-bundle_loader is for building -bundles :)

It's a simple change to the configure script, and it would be 
great if this could happen before OS X 10.4.

That's not true.  -bundle_loader does not generate a mach header 
load command, it is merely so that ld can make sure that all of 
your symbols are defined at link time (it will work for an 
embedded Python, try it).

You do need -undefined dynamic_lookup though, because 
-bundle_loader doesn't respect indirect symbols.  I'm not sure it's 
possible to make Python.framework get "imported" into the 
executable so that it's possible to -bundle_loader without 
-undefined dynamic_lookup (-prebind maybe, but I doubt it).

There's a reason why I use -framework in stead of -bundle_loader: 
you can only specify an application as bundle_loader, not 
Python.framework itself. This means you have to specify the 
Python executable, which makes it impossible to load extension 
modules (including all the standard extension modules) into an 
application embedding Python. I don't think this is acceptable.

err, this is a 10.3+ only request, and requires use of -undefined 
dynamic_lookup as well
