Actually, after re-reading your original message I think I misunderstood
and went off on a tangent.

If you are embedding python into a C++ app, then you will need the dlls and
all of the compiled python code. *.pyc. (Well most, not all). The exact
location of these files in the final build I'm unsure of.
