I'll check, but I see you running TeXLive 2021. I think you'll need TeXLive 2022.

It would be surprising if this function was removed from the LaTeX3 kernel.

[hanetzer]

Seems its a 'me' thing. Gentoo ships a slightly older version, and there's currently no work being done on updating. setup a chroot to get thru, but may be worthwhile to note you need a newer latex.

[dcpurton]

There is probably a warning in your log file that your version of LaTeX is too old.

[hanetzer]

True, there was, but it struck me as being 'wrong' as my installed version was 2021; I didn't realize that they were 'backdated' so to speak.

[dcpurton]

I'll note the minimum LaTeX version more clearly in the documentation for next release.
