I believe that epg is part of the standard emacs packages now.  It
should be available wherever Emacs is.

This isn't a bad idea. My elisp-fu is limited, but I think that I can
probably figure out how to do this.  It looks like epg-gpg-program is
set with this in epg-config.el.


(defcustom epg-gpg-program (if (executable-find "gpg2")
                                                              "The `gpg'
                               Setting this variable directly does not
                               take effect;
                               instead use \\[customize] (see the info
                               node `Easy Customization')."
                                 :version "25.1"
                                   :group 'epg
                                     :type 'string)

I actually have no idea.  I'm usually a Debian user, but liked the idea
of having a reproducible setup which was easy to move between
machines. Nix works pretty well, but there are a lot of rough edges --
like not having gpg linked to gpg2.
