It is not only a matter of packaging. Maybe XFree4 and QT are both compiled 
with the RENDER extension. This enables you to use antialiased fonts, but you 
are not forced to. If you switch to antialiased fonts, you won't get this 
messages anymore, but the fonts usually have to be re-configuered in KDE 
(->control center). You also should install some truetype fonts such as the 
microsoft fonts.

If you don't want to do this, you simply leave the system as it is - there is 
no problem with that. Just ignore the message.
