[Pkg-octave-devel] Error message about "empty_list_elements_ok"

I use up-to-date (May 1, 2005) Debian unstable on a PC. I use octave 
(2.1.69-1) and octave-forge (2004.11.16-7). I have downloaded the Debian 
sources "octave2.1_2.1.69.orig.tar.gz" and "octave2.1_2.1.69-1.diff.gz".

I have a large and complicated octave program that calculates 
curvelets". See "http://www.curvelet.org/". I get the error

     error: `empty_list_elements_ok' undefined near line 106 column 34

The error message does not appear until I type "lasterr". The string 
"empty_list_elements_ok" does not occur in the Debian sources or in the 
curvelet code. Weird. What is wrong?

fdct_usfft_demo_disp.m -- Displays the curvelet coefficients of an image

1. The low frequency (coarse scale) coefficients are stored at
    the center of the display.
2. The Cartesian concentric coronae show the coefficients at different
    scales; the outer coronae correspond to higher frequencies.
3. There are four strips associated to each corona, corresponding to
    the four cardinal points; these are further subdivided in angular 
panels.
4. Each panel represent coefficients at a specified scale and along
    the orientation suggested by the position of the panel.
