It will not change because /usr/lib64/libkdeui.so.5 is looking for some 
sybmbol that doesn't exist, ie. there is library mismatch, or some library is 
missing. 

Usually it means that library where libkdeui.so.5 is looking for a symbol is 
older, but it could be newer and symbol was for some reason removed. 
Developers are trying to keep backward compatibility, so symbol removal in 
newer version happens only when it is absolutely necessary. I (as non 
developer) can imagine that valid reason would be to much clutter collected 
trough the time that makes software performace suffer, and/or maintenace is 
near impossible. 

That means first look for older libraries that libkdeui.so.5 is depending on, 
then all other possibilites. 

Markus already posted the solution for this one. 
I would like to know what method he is using to find what is missing. 
I know only manual method:
- list all requires  
- look for packages that contain them
- check installed versions agains requirements
but I also know that packagers don't do that way, as it is taking too much 
time.
