OK, there were a couple of problems:

1) old *.elc file
2) I was creating a derived mode
3) Outside of the define-derived-mode expression, I was separately
using the construct:
(unless iop-alert-mode-map
  (setq iop-alert-mode-map (copy-keymap text-mode-map))
 (define-key iop-alert-mode-map (kbd "<prior>") 'view-previous-entry)
...

So, what was happening most likely was that the derived mode was
creating the mode-map, and this prevented the (unless iop-alert-mode-
map  from operating.

I moved the define-key inside the define-derived-mode expression.

Thank you all for putting up with this.
