That's the right way to deal with it - raise an exception when it detects that incompatible versions are being used. The bugs are in the binary packages that are dependent on SIP and PyQt - they need to be rebuilt when the internal ABI changes. Obviously I need to do a better job in documenting when those changes happen - but I would expect packagers to be slightly more on the ball than they seem to be.
