Hello,

Sorry Simon for the noise, this is just a quick feedback about my
debugging; next messages will be only to debbugs, you know how to track
it :-D 

Meanwhile I've learned how to test things in a dedicated environment,
thanks to some interesting tips [1] (I ignored before) adapted to Guix;
this confirms (ça va sanse dire) how powerful Guix is!

No, I've actually found a workaround - commenting out "(require
'org-tempo)" in my init.el - that works with my emacs configuration (and
package set) BUT there is absolutely no conflict between org-tempo and
elfeed-org.

I confirm that if I eval "(require 'org-tempo)" I get the previously
reported error and backtrace, I confirm that if I do not remove
(comment) "(require 'org-tempo)" in my "production" init.el elfeed does
not work as reported in the first message of this bug report.

Last but not least, I confirm I had no issues with the same manifest
(I've replaced ghc-pandoc with pandoc but that's tangent) and the same
init.el using Guix Emacs 26.3

So I ceated a directory dedicated to my tests in
~/.emacs-testing.d/test-elfeed, where I put "manifest.scm" and a
"test-elfeed.el" (both attached below, inline).

Well: if I do this

--8<---------------cut here---------------start------------->8---

[~/.emacs-testing.d/test-elfeed]-
giovanni@roquette: guix environment --pure --ad-hoc -m manifest.scm -- emacs -q -l test-elfeed.el

--8<---------------cut here---------------end--------------->8---

I get an emacs session with a running elfeed, and "(require 'org-tempo)"
is there.

This is manifest.scm:

 '("gs-fonts"
   "font-dejavu"
   "font-gnu-freefont"
   "unicode-emoji"
   "emacs"
   "emacs-org-contrib"
   "emacs-elfeed"
   "emacs-elfeed-org"
   "curl"
   "nss-certs"
))

This is test-elfeed.el:


[-- Attachment #1.4: test-elfeed.el --]
[-- Type: application/emacs-lisp, Size: 1898 bytes --]

[-- Attachment #1.5: Type: text/plain, Size: 494 bytes --]



So AFAIU there is no direct conflict between elfeed-org and org-tempo,
that conflict is apparent only in my full init.el configuration (and
package set) and probably is related to a combination of environment and
init.el configuration.

I'm going to investigate more and see what I can do to sort out things.

Happy hacking! Gio'
