Snow leopard and Qt/PyQt 4.8.x won't work

If you try to install, even with Homebrew the latest version of Qt the 4.8.x, you may end up haing a surprise like that :

ImportError: dlopen(/usr/local/lib/python/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

This is coming precisely from a Qt issue that don't seem to be resolved anytime soon, so anyway you're warned now, revert back to 4.7.x you have no choice. Except if you want to buy Lion :)
