export to lilypond

rosegarden 21.12 qt 5.15.2
which is what i get on archlinux

exports to lilypond 2.14 though i read that it detects the version of
lilypond on my computer.

lilypond is up to 2.22.2 though it still works with minor
editing of the .ly file (eg remove \lyricsto).
i have to change the \version too.

are there later versions of rg?
would compiling it be better than getting it from archlinux?
