There is no copy of Expat included in the source release of Python
2.1, so you must have got it from somewhere else...

So am I, but that is hard to answer until we find out what the exact
version of Expat is that you are using (expat is the underlying
library, not pyexpat), and until you can provide a test case that
demonstrates the problem...
