ESS is sounding like compilation is optional, and I never have.

Definitely. I may look into that. I pretty much just use Org and R, so
not super worried about it, but I really don't know enough to
understand what other packages ship with emacs that I could/should be
updating!

$ grep emacs /var/log/pacman.log

Yup, see the original email:

I can reproduce this with:
- emacs -Q
- putting this in the buffer

(add-to-list 'load-path "/path/to/ess/lisp")
(require 'ess-site)

- M-x eval-region on the above two lines

Thanks for the assistance!
