[PyQt] Failure to compile PyQt4 Python3.2

[Algis Kabaila]

Hi,

I want to upgrade from Python 2.6 to Python 3.2, including PyQt.  
So far I used PyQt installed as binaries from ubuntu 10.10 
repositories as well as Qt4 : 4.7.0ubuntu4.2.

I did not re-install Qt, available from nokia as source package:
qt-everywhere-opensource-src-4.7.2.tar.gz.  If that is the cause 
of the problem, please tell me and I will install it first.

The steps of installation in detail were:

The first step,  installation of python3.2 appeared to be ok -
./configure.py
make
make test
sudo make install
completed satisfactorily.
Next step, sip-4.12.1.tar.gz was expanded and installed in the 3 
steps:
python3 configure.py
make
sudo make install
Installation seemed to proceed without complaints.  The python3 
script invokes python 3.2.

PyQt-x11-gpl-4.8.3.tar.gz expanded ok. After
python3 configure.py was satisfactorily complete,
make
failed with the following tail of messages:

All of the tail listing is too deep for me to fathom. Your help 
will be greatly appreciated!
