I'm glad that it works for you too.

This is due to a missing DL_EXPORT macro needed for the shared extension
initialization function. See the following for more details:
http://sourceforge.net/patch/?func=detailpatch&patch_id=103185&group_id=5470
Using Modules/_curses_panel.c as an example, you need to change:
void init_curses_panel(void)
to:
DL_EXPORT(void) init_curses_panel(void)
I have submitted patches to Python CVS for the ones that I have come
across, but there are obviously more. Please submit patches for the
ones that you find.
BTW, you may also run into the following problem:
http://www.python.org/doc/FAQ.html#3.24
The above patch demonstrates how to fix this problem too.
Thanks,
Jason
