Did you get the qwt installer from here:
http://www.ettus.com/downloads/gnuradio/other_deps_with_installers/

The one from qwt's website is all messed up. I should also warn you to
not use the slider. The other ranged elements are fine, somehow they
messed up the slider. If you build pyqwt from source it works fine, I
have no idea why their installers are so wonky.
