It seems there is a way to fix this:

Would be nice to document this or make the build system find the libraries and

It would be really great if this could be sorted out because at the moment this

programming.. I know I must parse that other page but I don't have idea
how can i simply add new functions to module after its initialization
(Py_InitModule())? I'm missing something like
PyModule_AddCFunction().
This type of question really belongs to python-list aka
comp.lang.python which I CC-d now. Please keep the discussion on that
list.
Cheers,
Daniel

I vote for adding the Python package pubsub to the Python standard
library. It has recently been added to wxpython (replacing the old
wx.lib.pubsub package), but it has application to non-gui programs as
well.
For more information see: http://pubsub.sourceforge.net/.
If you are really
just curious, what's the largest python powered website in the world?
I'm afraid you'll need to define what you mean by python powered. If
the server side of a web application is written in 3 or more languages
and one of them is python, does that count? If yes, then probably
google and youtube
If I dump a Python dictionary into a file named data.pkl using
Pickle module on a Linux operating system, will the data contained in
data.pkl load fine in a Windows OS?
Yes.
I mean will I be able to load the dictionary data contained in data.pkl
just fine on Windows XP?
Yes.
