Just a wild guess: when you double-click you could have a 
different working directory than when you run from Project 
Builder. You could put some debug output in your embedding 
application (for instance print the working directory, or set 
the Py_VerboseFlag to 1 before calling Python), and the output 
will appear in the console window 

I'm also not 100% sure which Python initialize routine you need 
to call if your Python scripts want access to Carbon methods. I 
think Py_Initialize() may be good enough, but it could be that 
you have to use PyMac_Initialize() (as in MacPython). Or maybe 
you even need something completely different (i.e. 
Py_Initialize() plus some of the stuff in PyMac_Initialize().

Maybe someone else has already experimented with embedding 
MachoPython and has information to share?
