I forgot to mention that Celtk should Just Work with the official ltk, and I would build against that, but ltk classic kinda mangles error messages from Tk, and I tend to get a lot of those, so there are just a few tweaks (one?) to get the whole message legibly. Maybe those (it?) would be a good enhancement to Ltk?

I noticed that I also commented out ltktest classic at some point. Not sure why, but there should be no conflict with anything in Celtk.
