Pyrex problem - Py_NoneStruct

[Gary Stephenson]

I'm getting a clean generate, compile and link from my .pyx script, but when
I attempt to run the resultant .exe, I get:

    "The procedure entry point Py_NoneStruct could not be located in the
dynamic link library python23.dll"

Can anybody provide me with a clue here?  I've already cut down my script to
remove all references to None, Py_None, NULLs, etc, but to no avail.  fwiw
I'm using latest Pyrex and ActiveState build 232.

many tias,

gary
