Tim, does it byte-compile with emacs 23? for you.

I get what looks like some errors that will require editing.
When byte-compiling the version offered at the wiki you cite:

http://git.savannah.gnu.org/cgit/emacs-tiny-tools.git/tree/lisp/other/folding.el?h=devel

Maybe the debian pkg has an edited version?
