I don't recall it.

The Octave bindings can't use (in a straighforward way) "-rpath", and=20
so I use LD_RUN_PATH instead of LD_LIBRARY_PATH. The difference is=20
that LD_RUN_PATH is stored in the executable. In cf/pkg_octave.in:

# 'mkoctfile' does not accept -rpath, use LD_RUN_PATH

plplot_octave.oct plplot_octave.o: plplot_octave.cc
   LD_RUN_PATH=3D`pwd` $(MKOCTFILE) -v -I. -L. plplot_octave.cc ...

install_octave: ...
=2E...
   LD_RUN_PATH=3D$(LIB_DIR) $(MKOCTFILE) -v -I. -L. plplot_...

I don't know if this will work for the java demos, but I guess that=20
it will,
