Sorry for the somewhat irritated and unfriendly tone of my response (I
meant: if I had had the time to debug this I wouldn't have sent that not
so helpful note in the first place).

However, it seems the reason for the breakage is the following:

I use gnus from the development repository http://git.gnus.org/gnus.git,
so that ~/share/emacs/site-lisp/gnus is a symlink to the `lisp'
subdirectory of my local gnus repo clone.

I my ~/.emacs I have

(add-to-list 'load-path "~/share/emacs/site-lisp")
(let ((default-directory "~/share/emacs/site-lisp"))
  (normal-top-level-add-subdirs-to-load-path))

and this adds also gnus/gnus-fallback-lib/eieio to the load path, so
that the files there shadow the regular eieio stuff.
