ImportError: No module named sipconfig

Und dieses mal macht das Paket dev-python/PyQt4-4.3.3 Probleme und lässt sich nicht installieren. Emerge bricht mit folgender Fehlermeldung ab: 

# emerge -uND world

Das geschulte Auge sieht sofort, dass ein Problem mit dem Paket dev-python/sip vorhanden ist.

Lösung

Die Lösung dieses Problems ist relativ einfach: ein emerge dev-python/sip startet die Neuinstallation und and danach lässt sich auch dev-python/PyQt4-4.3.3 problemlos kompilieren: 

# emerge -av sip

These are the packages that would be merged, in order:
