Ah ha! Fantastic. I didn't think of looking at the older repositories (something I would never have done with Debian). I have found not only libxaw7 but also the dependencies it has (libxmu6 and libxpm4) there. They seem to have installed just fine.

I'm now off to try emacs with X but need to re-download the deb for that so it'll be a little while.

Thanks again,
eric
