ImportError: No module named qt

Hi all

I have just upgraded my system to FC4 because I started to get problems
with some programs that use python and hope that the upgrade from FC3
would help.

NO SUCH LUCK!!

below is the error I get if I try to run the hplip toolbox program.



[laurence@athlon ~]$ hp-toolbox
Traceback (most recent call last):
  File "/usr/local/bin/hp-toolbox", line 41, in ?
    import base.async_qt as async
  File "/usr/local/share/hplip/base/async_qt.py", line 85, in ?
    from qt import *
ImportError: No module named qt


question now is where has it gone?
how do I get it back?
I think it should be part of PyQt, but that is supposed to be installed.
it used to work fine up to a couple of weeks ago

ANY hints would be useful

TIA
Laurence
