I suppose line 8 was this one:

     def __new__(self, cookie c):

When you instantiate the class you're going to pass a Python object as 
argument c. And you are instructing Pyrex to convert that object to "void*" 
which isn't possible since there is no pointer type in Python. Instead you 
can use Python integers to store the pointers:

     def __new__(self, long c):
         self.c = <cookie*>c
