Ah, sorry, I had understood that you are trying to use the Gnus version
that comes with Emacs but with the gnus-sum.el that comes with Gnus' git
version.

I also run the Git version of Gnus, and that's what you need to do:

Once: clone the git repo && ./configure && make
Regularly: git pull && make

And in my ~/.emacs there is

  (add-to-list 'load-path "~/Repos/el/gnus/lisp")
  (add-to-list 'Info-directory-list "~/Repos/el/gnus/texi")
  (require 'gnus-load)

which you have to adapt to your Gnus checkout directory accordingly.

Yes, it is.  However, in the current case you could only use

  (advice-add 'gnus-summary-exit :override
              #'your-version-of-gnus-summary-exit)

which would override the normal version with your patched version.  I
guess in this situation, it is better to apply your patch to the git
version, run it for some time, and then report back to the bug report
that nothing breaks (if nothing breaks, of course).  Then someone will
hopefully commit it to Gnus.  If nobody reacts, feel free to ping me, I
have push access.

Bye,
