I run into the exact same problem as Patrick a couple of days ago.  I have 
submitted a patch to the Python team that allows "import PyQt4.QtCore" to 
work.  You can find the patch here: 

I would vote against renaming PyQt4.QtCore to QtCore for the statically linked 
PyQt because then it would mean that you need "from PyQt4 import QtCore" if 
you have linked PyQt4 dynamically and "import QtCore" if you have linked it 
statically.  I use static PyQt4 in Windows (for ease of deployment), but in 
Linux I use the dynamic version, so this solution would be inconvenient for
