I don't either, but I have the libs installed.
The libs aren't so difficult, but what about the resource requirements? I run a GNOME 1.4 desktop, and as a simple test, I started konqueror to see what resources the KDE infrastructure would use. It seems pretty staggering:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

The sixth column, RSS, is the important one. I have plenty of RAM on my system, but even so Mozilla doesn't look so big in comparison.
