It certainly should not break anything, I need a detailed bug report if it
does.

Are you using LD_LIBRARY_PATH to run the KDE3.2 binaries or -Wl,-rpath
when linking?
If the libraries have the same SONAMEs as the system ones, but are
incompatible (which is a bad idea but some projects do it from time to time),
then -Wl,-rpath is the only way to make prelinkable both system and
/opt/kde3.2 KDE binaries.  Though, as I said, even if you prelinked
the KDE3.2 binaries against system libraries, they should still run,
although not get any advantages from prelinking.
