Spamc -V does give me a version number, so that seems to be working. I
added the code you recommended, so the full splitting/spam-oriented
lines of my .gnus are:

| (setq nnmail-split-methods 'nnmail-split-fancy
|       nnmail-split-fancy '(| (: kevin-spamassassin)
|                              "mail.misc"))
|  
| (defun kevin-spamassassin ()
|   (save-excursion
|     (save-restriction
|       (widen)
|       (if (eq 1 (call-process-region (point-min) (point-max)
|                                      "spamc" nil nil nil "-c"))
|           "spam"))))

I can receive mail still---all seems to be working, but no spams have
yet been filtered. Are there steps I need to take directly with
Spamassassin to get it working?

Thank you very much for all of your help here! This is the farthest I've
yet gotten with this.
