What about a separate package?  E.g.

	(define-public pinentry-emacs
	  (package
	   (inherit pinentry-tty)
	   (name "pinentry-emacs")
	   (inputs
	    `(("emacs" ,emacs)
	      ,@(package-inputs pinentry-tty)))
	   (arguments
	    `(#:configure-flags '("--enable-pinentry-emacs")))
	   (description
	    "Pinentry provides a console and an Emacs interface that allows users to
	enter a passphrase when required by @code{gpg} or other software.")))

I haven't delved into packaging so far.  I have read the manual but I'm
unsure about the best practice for local hacking.

I have set GUIX_PACKAGE_PATH=~/.guix-packages, then

	> cp ~/.config/guix/latest/gnu/packages/gnupg.scm ~/.guix-packages/
	> chmod +w ~/.guix-packages/

Then add the above the the file, plus a

  #:use-module (gnu packages emacs)

at the beginning.

Now if I do

	> guix package -s pinentry-emacs
	guix package: warning: failed to load '(gnupg)':
	no code for module (gnupg)

Notive the error at th beginning:

	guix package: warning: failed to load '(gnupg)':
	no code for module (gnupg)

I don't understand this.

That said, is this the commended way to proceed?  Or should I work from
a local checkout of guix?  What about the value of GUIX_PACKAGE_PATH then?
