What I'd do is carefully remove all traces of PyQt and sip from your
system. Start with SuSE's rpm's, then do a thorough search for bits
you might have added yourself. Then decide whether you want to build
PyQt with Python 2.0 or with Python 2.1 - the latter has some
advantages. If the base Python is good and free from PyQt, start with
sip 2.4 again and continue with PyQt 2.4
