This is what I've done, but with a complete recompile from a clean unpack, 
to be safe. This would appear to have solved the problem of picking up the 
kde 2 libraries.

This was the first one I tried, I didn't work. I also tried editting the 
duplicate files in PyKDE-3.2.4/sip/kde30/ but without effect. Are one set 
of these generated from the other, or do they serve different functions.

Not with the lovely automation of bash it wasn't :)

I think that was some sort of aberation on my part, it would appear that the 
files are now linking without resorting to symlinking so.4 to so.3.


Here is the (possibly different) problem I'm faced with, for some reason 
related to PyQT or sip kdefx is failing to link correctly, with the 
follwing error reported on make install:

make  install-data-hook
make[3]: Entering directory 
`/home/alex/stuff/software/python/PyKDE-3.2.4/kdefx'
(cd /tmp; 
PYTHONPATH=/usr/lib/python2.2/site-packages:/usr/lib/python2.2/site-packages 
/usr/bin/python -c "import kdefx")
Traceback (most recent call last):
  File "<string>", line 1, in ?
  File "/usr/lib/python2.2/site-packages/kdefx.py", line 37, in ?
    import libkdefxc
ImportError: /usr/lib/python2.2/site-packages/libkdefxcmodule.so: undefined 
symbol: sipCast_QCommonStyle__FPCvP7_object

Having looked at the ldd output of these files I haven't spotted anything 
obviously wrong, I've posted the relevant information at:

Thankyou for all the help, I'll have another look at this tonight.
