What I found when trying to install it for OSX is that Qwt5 must be  
inside the PyQt space (ie in the Pyqt folder), because it's loaded  
with "from PyQt4.Qwt5 import *".

If you have multiple PyQt installations, make sure you're installing  
Qwt in the same PyQt that Qgis is loading.


PS. are there a lot of Qgis plugins now that use Qwt5?  For OSX  
packaging I may need to bundle Qwt5 in the Qgis app, at least for Qgis  
1.1.
