This test will tell you if LD_LIBRARY_PATH works with a given program:

$ objdump -p $KDEDIR/bin/konqueror | grep PATH
  
RPATH       /usr/local/kde3-r487700/lib:/home/thiago/programs/src/kde3/qt-copy/lib:/usr/X11R6/lib
  
RUNPATH     /usr/local/kde3-r487700/lib:/home/thiago/programs/src/kde3/qt-copy/lib:/usr/X11R6/lib

If neither RPATH or RUNPATH are present, LD_LIBRARY_PATH works. If both 
are present, it works. If RUNPATH is alone, it works.

If RPATH is alone, it will not work. This is the standard KDE build on 
Linux. You can change it by:
1) --disable-rpath
or
2) --enable-new-ldflags

BTW, now that I think of it, I think of it, I guess I remember why libtool 
had a problem in the first place. It wasn't because of 
-Wl,--enable-new-ldtags. It was because of -Wl,--as-needed, which is 
turned on along with it.
