OK, I had time to look into this more ...

It is a "load path" issue.  Here is the value of my default
'load-path' (sorry for the length!):

       ("/usr/share/emacs21/site-lisp/oneliner-el"

       "/usr/share/emacs/21.4/lisp/emacs-lisp"
       "/usr/share/emacs/21.4/lisp/calendar")

       
Once I added "/usr/share/emacs/21.4/lisp/gnus" to the front, I was
able to use the 5.9.0 version of 'gnus'.  (Note a copy of that path
*is* in the fifth-to-the-last entry above).

Some questions:

  o Where is 'load-path' initialized?  

  o Should the "/usr/share/emacs21/*" entries precede the
    "/usr/share/emacs/21.4/*" ones?

  o Both "/etc/emacs" and "/etc/emacs21" exist ... is that correct?

  o Might the problem have something to do with the contents of
    /etc/{emacs,emacs21}/* ?

  o Am I using older versions of *other* things, too (e.g., 'eshell')?


Finally, here are all relevant installed Dapper packages:

       emacs-goodies-el/dapper uptodate 26.4-1
       emacs21/dapper uptodate 21.4a-3ubuntu2
       emacs21-bin-common/dapper uptodate 21.4a-3ubuntu2
       emacs21-common/dapper uptodate 21.4a-3ubuntu2
       emacs21-el/dapper uptodate 21.4a-3ubuntu2
       emacsen-common/dapper uptodate 1.4.17


Thanks for the help!
