I don't think that is the case:
====
kim at sirius:~/saft-octave/solver/saft/octave/ignore/my_code$ ldd
../install/bin/octave
	linux-gate.so.1 =>  (0xffffe000)
	liboctinterp.so =>
/home/kim/saft-octave/solver/saft/octave/ignore/install/lib/octave-3.0.0+/liboctinterp.so
(0xb75eb000)
	liboctave.so =>
/home/kim/saft-octave/solver/saft/octave/ignore/install/lib/octave-3.0.0+/liboctave.so
(0xb6d74000)
	libcruft.so =>

(0xb6d27000)
	libumfpack.so.1 => /usr/lib/libumfpack.so.1 (0xb6c6f000)
	libamd.so.1 => /usr/lib/libamd.so.1 (0xb6c67000)
...

I remember something about a variable I could set in octave and then
it would show how it tries to load function files, but I can't find
anything about it now. Can anyone give a hint about what that
functionality might be called?
