I'm quite new to Debian/dpkg packaging in general, and have no
familiarity with Launchpad recipes, but it sounds like your package
might not be loading all of the startup bits expected by
/usr/share/doc/emacsen-common/debian-emacs-policy.gz.  For starters,
does M-x load-library RET debian-startup RET from your Launchpad builds
actually point somewhere?  If so, does the `startup' library load it?
That `debian-startup' file is the entry-point for Emacs dpkg packages
setting up their autoloads and the like, and yes, unfortunately, this is
a big fat distropatch. :-)

Ubuntu's emacs-snapshot packaging may have changed this whole
infrastructure in some way that I'm not taking account of, but I would
expect that many elisp packages in Ubuntu are largely unchanged from
Debian and simply expect this to work.

I agree that it's a pretty minor complaint if the rest of the package is
working great, but dpkg packages for Emacs features are still useful in
spite of package.el, particularly if they have non-elisp dependencies,
e.g. the `auctex' package, or the `maildir-utils' package (containing
the `mu' maildir indexer which is the binary dependency for djcb's
`mu4e' Emacs mailclient).

HTH,

WGG
