That could be because KDE binaries come with the path to the library hardcoded 
by the linker. That is, they have a search path in the RPATH record of the 
header that takes precedence over LD_LIBRARY_PATH. You have to disable rpath 
(--disable-rpath) in order for LD_LIBRARY_PATH to work.

Indeed, all KDE programs depend on kdecore, which in turn depends on dcop and 
kdefx. GUI programs also depend on kdeui.

I don't think I understand the impact of the instrumentation. What happens if 
you run an instrumented kprint with the standard kdecore?
