Did you follow the link to the definition to figure out what's going on? Ah... I found this: https://github.com/dholm/tabbar/commit/6d5a6935879. IMO it's wrong to do that, but that is of no concern here. > Anyway, that aside, what version of emacs is this available from? Emacs 24.3. A forward compatibility implementation for older versions is available at https://elpa.gnu.org/packages/cl-lib.html. I didn't find any information about what minimal Emacs version Notmuch expects but https://notmuchmail.org/emacstips/#index1h2 implies that it is 24.1. IMO it would be reasonable to expect at least 24.3, 24.5 or even 25.1. See https://www.gnu.org/software/emacs/history.html for release dates. Or you might want to just drop this commit. Or we could update the FAQ to mention that one has to install cl-lib from GNU ELPA if one uses such an ancient Emacs release.
