It's a bit more subtle than that (especially when using XCode with 
the various OS SDK's installed).

Normally, from XCode, you can just "add framework", select Python (in 
/System/Library/Frameworks) and then do #include <Python/Python.h> 
and everything will work.  That's the easy answer.

...unless you try to target the 10.2.7  SDK (to try to build an app 
that works under 10.2.7 and would use a user-installed 
/Library/Frameworks/Python.framework) at which point it won't work... 
Turns out that XCode actually looks in 
/Developer/SDKs/MacOSX(whatever).sdk/System/Library/Frameworks, and 
there is no 
/Developer/SDKs/MacOSX10.2.7.sdk/System/Library/Frameworks/Python.Framework 
so even though you've added Python.framework (and can even see 
Python.h in xcode) it won't find it when building (and you have to 
manually add an include path, and you can't use the framework style 
include).
