[Pythonmac-SIG] locating Python.h

[Michael VanLandingham]

If you're using Xcode, you just #include <Python/Python.h> in your  
source file, then add the Python framework to your project (in Xcode,  
right click on your project file in the "Groups & Files" pane, select  
"Add->Existing Frameworks...").  You might need to configure the build  
rules to make sure the right version of the framework is found first,  
but on my system, this just worked.

If you don't add the framework to the project, you get the linker  
errors that you described.

If you're not using Xcode, and instead are using gcc on the command  
line or makefile, then you need to add the right flags so that it can  
find the framework, etc.
