You're probably right.  I've never encountered the problem because I use 
CMake for everything.  It automatically pulls in library dependencies 
and links the executable explicitly to all libraries (at least if the 
project providing the libs uses export_library_dependencies properly).

Inside the kdelibs build tree CMake will link the executables to 
everything they need so the library search paths will not be needed. 
Perhaps they could be built with the install tree rpath only.  I'm not 
sure what the precedence is though so that might conflict with the 
executable's rpath.  Someone will have to investigate.
