Problem running ktoon

I've just realised I can't post an image so here goes:

When I try to run ktoon on FC3, I get a pop-up window that asks me to choose one of a series of application names (I think they are anyway), for example:

avcstat
automount
authconfig
atrun
atd
apmd

etc

if I choose to cancel, I get another window that says:

which: no ktoon in (/tmp/app/1/sbin:/tmp/app/1/bin:/tmp/app/1/usr/bin:tmp

and so on.

I'm curious as to the problem and how to fix it.

Any help will be most appreciated.

Regards,

Patrick
