[Pyrex] pyCdk SystemError: Objects/longobject.c:240: bad argument to internal function

[Dog Walker]

Trying to run a pyCdk example in Python 2.3 using Pyrex 0.9.3 produces:

linux:/home/dw/pycdk/examples # python calendar.py
Traceback (most recent call last):
  File "calendar.py", line 13, in ?
    calendar = cdk.Calendar(screen, 0, 0, title, d, m, y, curses.A_BOLD, 
curses.A_BOLD, curses.A_BOLD, curses.A_REVERSE, curses.A_REVERSE)
  File "cdk.pyx", line 511, in cdk.Calendar.__new__
SystemError: Objects/longobject.c:240: bad argument to internal function

I think that the problem is that a call is made to a python function with an 
int argument where the function only accepts longs. I would like to either 
fix pyrex 0.9.3 or pyCdk's cdk.c. The fix I see on Python involves python.

(Are there older versions of Pyrex which don't raise this error?)
