Ahah! Thank you very much.
Is there a way for me to get a listing of all past versions of a
package? For example, I knew that I wanted "whatever python2.3 was
before 2.3.1-1", which turned out to be 2.3-4 -- and I found that out by
browsing through the pool directories. Is there an easier way?

Cool. Looks like python2.3-tk was the only package that griped, and
that was easy enough to fix.

Umm, let's just skip it. I think I read the dependencies wrong.

Okay, I've used the = method, but the echoing thing is a great tip!
Is there a way to mark things on "hold" via the apt tools? It seems
like apt-get respected dselect "hold" last time I used it ... or was I
mistaken?
Also, what's the best way to find out that a newer version is available?
Looks like that's what the "subscription-package tracking system" form at
http://packages.qa.debian.org/p/python2.3.html does?
Thank you very much for all your help!
