If you have read the KDE TechBase pages you know that I support it with 
KDE-4.4.

I am using the same methods to upgrade from 4.4 to 4.5 that I used to 
upgrade from 4.3 to 4.4 and they are not working.  I see this as a problem.

Yes, that is a point.  I forgot to mention that I have also set:

CMAKE_INCLUDE_PATH=/opt/KDE-4.5/include:/usr/X11R7/include

So you can see that something is wrong here.

You don't have to clean the PATH, just put the new stuff at the front:

QTDIR=/usr/local/Trolltech/Qt-4.6.3
KDEDIR=/opt/KDE-4.5
PATH=$KDEDIR/bin:$QTDIR/bin:/usr/X11R7/bin:$PATH

I think that I have set everything, but it still doesn't work.  Note 
that I use a script to build so everything is set every time.

I can use hacks to build it, but I really need to find out what is wrong 
to write reasonable instructions.
