embedding Pyd in Windows program

[Matt via Digitalmars-d-learn]

I'm trying to build a simple platformer using SDL2 and python to 
script entities, but I'm struggling to include Pyd. I'm using DMD 
v2.066.1, with dub as the package manager, and derelict for the 
SDL2 bindings.

Now, when I add Pyd to my dub.json everything works fine, but as 
soon as I add py_init(), my code compiles and links fine, but I 
get "ImportError: No module named site". Have I done something 
wrong? Can anyone shed some light on this? Or am I asking in the 
wrong place?

Any help would be very much appreciated, and I can provide code 
on request if that helps.
