Thanks baz walter for your reply.. Thank you for stating my problem
clearly.. But could you please tell me in detail like in which sequence i
should install the qt to make it work with python3.. i've tried installing
SIP.. But again the same error..
Are u trying to say that i should again install SIP and PyQt by downloading
from sources(not from ubuntu repositories)... If u say yes then if i have to
install it from the sources do i need to specify any --prefix options like
in ./configure to install it to the directory where python3 is installed?
I've installed python3 in /home/jeba/Python3.1.1. I've not specified any
--prefix options in installing python 3.1.1. Can u please tell me clearly by
spending your precious time?? I'm completely new to ubuntu and pyqt.. And
one more question.. Under configuring PyQt in the website it is stated that 

to configure SIP by executing the configure.py script. For example:

python configure.py

          If i issue this command again it'll run from 2.6 installation..
Will it not create the same problem again??? Plz. explain me in detail.. I
don't want to mess up this time..
