Well, the first rule of embedding Python is that you probably  
shouldn't embed Python.  It's generally preferable to have Python on  
the outside, and then whatever else on the inside loaded by extension  
modules.  This is the most supported configuration on all platforms,  
and is the easiest to implement correctly.

That said, it sounds like you need to link to Python.framework.   
However, this is tricky because it's likely that the next version of  
Mac OS X won't ship with Python 2.3, so your app could very well  
break if you link against the system Python...  It's probably better  
to compile your own and statically link it in, but it really depends  
on what you're doing with Python.
