We've had some patches in re the mop package name and other stuff to 
make it more portable. One user did a major cleanup of Cello but never 
got to the point where it would be released. And I am moving to the web 
with a new project based on qooxdoo. Doubt I'll ever get back to Cello.

ie, it is very close to being a dead project. Oh, and I only know of one 
person for sure who got it all working.
