I did the same over the last week or so. It wasn't too hard.

Well, having not written cello or cells-gtk, but now used it, I guess I am 
somewhat a neutral observer: GUI programming can get very messy very fast. It 
appears to me that the cells approach really does manage the complexity of 
the code nicely. And WRT to the implementation of a GTK binding for lisp, and 
what I can see studying Vasilis's code, it seems it made the implementation 
more elegant too.

Cello is the "cells" in "cells-gtk"  You loaded cello to get things running.

I am working with Andras on this. He has the cmucl stuff working. The belief 
was that the tarball version supported cmucl, but that hasn't been my 
experience. (And there is more to it than not finding the libraries). 

I am going to make some cvs commits, maybe later today, to fix some things 
with tree-view selection on #-Clisp... and some other stuff. I hope to get 
the cmucl patches in there too..
