This appears to be a problem with emacs22. Quoting the attached DpkgTerminalLog.txt:

In natty, the missing file seems to be provided by packages ruby1.8-elisp and ruby1.9.1-elisp

Upstream bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=557190 appears to attempt to address this, but is a fix for emacs23. Somehow this still affects emacs22. http://packages.ubuntu.com/natty/ruby1.8-elisp says emacs23 but not emacs22 satisfies the dependency on "emacsen". Is this an Ubuntu sync error, or a problem in one of the upstream packages?
