I think it's definitely an issue with PyCXX. I installed the latest
version of PyCXX and tried their test example program, and got the
dreaded "Abort trap":
bash-3.2$ python
Python 2.6.2 (r262:71600, Sep 27 2009, 13:41:53)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import CXX.example
CXX is installed.
The support files you need are in the PYTHON/etc/CXX directory.
The include files are in the distutils include path already.
Just refer to them as "CXX/CXX_Objects.h", etc.
range object created 0x1003140b0
range object destroyed 0x1003140b0
>>> CXX.example.test()
Example Test starting
Trying to convert a NULL to an Py::Int

bash-3.2$ pwd

Note that installing PyCXX and their test program was not easy. I
watched their "python setup.py install" fail repeatedly, then I would
copy missing files where they should go, and iterate (about 6 times
I've cc'd the PyCXX maintainer Barry Scott. Barry, do you have access
to an OS X 10.6 install, since it seems PyCXX is broken there? If
not, I can give you an account on a machine at University of
Washington. PyCXX is the single component of Sage
(http://sagemath.org) that is holding us back from finishing the OS X
10.6 port.
