[O] bug#29329: 27.0.50; Missing requirement in org-gnus.el

[Glenn Morris]

Speaking for the version in Emacs, apart from org-gnus the warnings are:

In end of data:
org-irc.el:255:1:Warning: the following functions are not known to be defined:
    erc-save-buffer-in-logs, erc-logging-enabled

(I haven't looked at the code.)
