OK, That looks like it is probably it (changing to just mod_python and then importing pyexpat does cause the seg fault). The problem is that after upgrading the installed library to expat 1.95.8 (same as Python -- see below), and restarting Apache, I still get seg faults. Do I need to rebuild Apache, mod_python, or vampire? I wouldn't have thought so if they are dynamically linked...
