I've been requested to create an application with a webview in it.
I've tried to import QtWebKit module but I have this error:

Traceback (most recent call last):   File "", line 1, in
   ImportError:
  dlopen(/Library/Python/2.6/site-packages/PyQt4/QtWebKit.so, 2): Symbol
  not found: _kCFWebServicesProviderDefaultDisplayNameKey   Referenced
  from: /Library/Frameworks/QtWebKit.framework/Versions/4/QtWebKit
  Expected in:
  /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation

It's the only one module that returns this error. All other installed modules are ok. The file /Library/Python/2.6/site-packages/PyQt4/QtWebKit.so exists.
What could the problem be?
Thank you all.
I was able to fix the problem by upgrading to MacOSX Lion, but if that is not an option I would just ensure that PyQt4 is not using qt4.8, which is where this issue was introduced. If I remember correctly, everything works well with qt4.7.4
