Try looking for md5.so - it'll probably be somewhere like 
/usr/lib/python2.5/lib-dynload. When I said sys-prefix I meant the 
--exec-prefix configuration option, but actually I'm not sure what 
determines where shared libraries end up.

At least knowing what you are looking for should help. This may affect 
other modules that use extension support.
