Sorry, I have no idea how to help you any further. I have given you suggestions of how to debug it yourself, and that is now probably as far as I can go. Whatever this environment is you are using, it seems to even screw up your ability to debug it. I'd suggest going to a mailing list that deals with the environment. Better still, perhaps use a completely different environment if you can. Alternatively forget about using mod_python and use a web server which is implemented in pure Python. For example, use Paste WSGI web server and run any WSGI capable application/framework on top of it. That way you will not have to deal with Apache in the first place. What is so special about this uClibc environment that you have to use it and what is the requirement you have that you must run Apache and mod_python?
