I don't understand why you get this, it works for me and I can't reproduce it with "emacs -Q". Does the following recipe works for you?: 1. emacs -Q 2. Evaluate the following code (for example, paste it into *scratch* buffer and "M-x eval-buffer"):
test.el
Description: application/emacs-lisp
3. M-x guix-all-available-packages 4. RET on any package that is not installed and press "Install" button in “*Guix Package Info*” buffer. For me “*Guix REPL*” is shown and the following output is printed:
scheme@(guile-user)> (process-package-actions #:install '((151687520 "out")) #:upgrade '() #:remove '() #:use-substitutes? #t #:dry-run? #t) The process begins ...

It is already available in a “*Guix Package List*” buffer: you can mark packages with "d"/"i"/"^" ("u" is for unmarking) and execute an operation with "x". As for me, I prefer to keep buttons in a “*Guix Package Info*” buffer as they are now. It's just an alternative way to install/delete a package: if you want to make a transaction of several actions – use a "list" buffer, if you just want to install some package, you can do it by pressing a button in "info" buffer. -- Alex Kost
