That sounds logical, but that would mean that: KoStore.o was correctly 
build against Qt-3.2.1 and now it can't find it when it is linked.  Doesn't 
make much sense does it??

Thanks for your suggestion.  it lists the whole command line with:

-L/usr/local/qt-3.1.2/lib
-L/usr/local/qt-3.2.1/lib

But it only lists 3.2.1 in the list.

So, that is the problem.  I must have kdelibs that are still linked against 
3.1.2.

I thought that I relinked KDE but I checked and it still has: "*.la" files 
with: "qt-3.1.2" in them.  :-)

I have a script that deletes all: "*.la*" files that contain a given 
string, but I must have screwed up when I used it.

Thanks again.
