I fixed the "parse error" problem somehow.
Deleted the cdk.c and cdk.so files.
Ran setup.py install in the pycdk directory which generated
a new cdk.c and cdk.so.
Ran a couple of the pycdk examples and each failed for the original
reason. 
Searching the cdk.c file, I get no hit on "PyInt_AsUnsignedLongMask".
That failure leads me to believe that the fix had no effect.

Here is what Pyrex/Compiler/PyrexTypes.py looks like now:

-----------------------------------------------------------------
class CULongType(CIntType):

    to_py_function = "PyLong_FromUnsignedLong"
    from_py_function = "PyInt_AsUnsignedLongMask" # from 'PyLong_AsUnsignedLong' per Greg Ewing

-----------------------------------------------------------------
Python version:

Python 2.3+ (#1, Sep 23 2003, 23:07:16)
[GCC 3.3.1 (SuSE Linux)] on linux2
        

I can "fix" some of examples (perhaps all) by using explicit conversion to long:
example, long(curses.A_BOLD) rather than curse.A_BOLD.

I would rather put this fix in the cdk.pyx file. That's what I was trying to do
when the "parse error" raised its ugly head. Should try again now I guess.
