Ok, so you're definitely running new enough versions. The error
message refers to a QwtWheel error. Is this the same error regardless
of what type of range style you are trying to use (slider, wheel,
counter, etc.)? Or does it change depending on which type of style you
are trying to use?

If it's the same error all the time, that would suggest to me that
there's some error in what you've built yourself. Perhaps something
didn't configure properly when building Qwt or PyQwt?
