[PyQt] ImportError on QtGui. PyQt4.4 commercial

[Darryl Wallace]

Hello,

I've just installed:

Qt4.4,
SIP 4.7.5
PyQt 4.4

On Ubuntu 8.04.

Everything installed fine.  But now upon attempting to import QtGui I 
get the following error:

from PyQt4 import QtGui
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /usr/lib/python2.5/site-packages/PyQt4/QtGui.so: undefined 
symbol: sipNm_QtGui_QLCDNumber

Any ideas?

Thanks,
Darryl
