OK. Sorry for the typing mistake :-(
Ofcourse the link can be full path or relative path.

Is there someone out there to build an RPM?
Also on my dual 800 it took quite a while to get ready.

I was using it on qt-only projects. I can't say how qt3 relates to the 
installed kde version.

Is that kde-stuff?

KDE is based on qt and bacause of that IMHO it is not advisable to use 
incompatible versions of both in one project. 
In my case I follow the rule:
If I do a qt-project I use qt3, if I do a kde project I use the version of qt 
kde is based on.
The problem is not a problem of the IDE.

--------------------------------
In my description I forgot to point out that I did an additional link for the 
qt-lib:
cd /usr/lib
ln -s qt3/lib/libqt.so.3 libqt.so.3

otherwise the linker complains for a missing qt-lib.
