Thomas, (above was offlist, applies to OS X 10.4.10 on PowerPC G4)
1. I have deleted the  ~/.octave_packages file but *not* the octave-2.1.71
installation and tried again:
octave-2.9.16:4> pkg install ~/Desktop/odepkg-0.3.3.tar.gz

2. Apparently successful (see below for demo output and I also got the
graph). The installation log still produced "tons" of warnings re multiple
definitions but no errors at the end.

octave-2.9.16:5> demo ode5r
ode5r example 1:

 A = odeset ('RelTol', 1e-1, 'AbsTol', 1e-2);
 [vx, vy] = ode5r (@odepkg_equations_secondorderlag, [0 2.5], [0 0], ...
    A, 5, 2, 0.02, 0.1);

 plot (vx, vy(:,1), '-ob;y, x2;', vx, vy(:,2), '-or;x1;', ...
    vx, ones(length(vx),1)*5, '-og;u;');

 % ---------------------------------------------------------------------
 % The figure window shows the state variables x1, x2 as well as the
 % input signal u and the output signal y(=x2) of a second order lag
 % implementation (cf. the control theory). The function ode5r was
 % called with an option argument A that has been set before with the
 % command "odeset" and with further parameters "5, 2, 0.02, 0.1" that
 % are passed to the set of ordinary differential equations.

3. octave-2.9.16:6> pkg install ~/Desktop/signal-1.0.4.tar.gz
mkoctfile: stripping disabled on this platform

Apparently now successful also without any errors at the end. Again "tons"
of warnings re multiple definitions and still the above stripping disabled
comment.
Thanks.
Henry
