Thank you very much.
That is exactly what I was overlooking.
Now, I've got the package loaded, but unfortunately the plot is not showing up.
I'm still on a Mac, and running the following code:
octave-3.2.3:30> L = tf(3e4 * [0.0025 0.1 1], [0.01 1.03 3.03 3.01 1]);
octave-3.2.3:31>
octave-3.2.3:31> bode(L)
octave-3.2.3:32>
octave-3.2.3:32> print('figure.ps', '-deps')
I thought the bode plot would show up, but it didn't. However, figure.eps was
produced and looks correct.
Do I need to take one more newbie step in order to get the plot to show up?
In installed GNU Plot:
G N U P L O T
Version 4.2 patchlevel 6
last modified Sep 2009
System: Darwin 9.8.0
Thanks for any feedback or insights.

>From octave 3.2,
** The Control, Finance and Quaternion functions have been removed.
These functions are now available as separate packages from
http://octave.sourceforge.net/packages.html
and can be reinstalled using the Octave package manager (see
the pkg function).
as in written in http://www.gnu.org/software/octave/NEWS-3.2.html
You have to install the control package first.
You can confirm whether it is installed or not by
octave> pkg list
If you do not find the control package, you have to install it by pkg install
command.
BTW, DEMOcontrol is not valid. It is
octave:3> controldemo
and
you can see
