Steve,
Many thanks! As it turns out, I just installed a group of programs, following the suggestions in the "perfect Setup" tutorial for Debian Etch at
http://www.howtoforge.com/perfect_setup_debian_etch_p4
-- and now the cpan module is working from my terminal! It must have been enabled in the process. As you note, cpan is part of the standard Perl distribution, but for some reason, it wouldn't launch earlier. But I may just use apt-get for most, if not all, of my Perl modules, instead of cpan.
I didn't know about the 'apt-cache search' command, which is a very good thing indeed! Many thanks for the help. I'm enjoying apt-get a lot more than RedHat rpms (:->)
