According to https://docutils.sourceforge.io/docs/user/emacs.html, rst-mode is part of Emacs since version 23.1. But Emacs 24.3 includes a "significantly updated version". For this reason, "builtin" is set to version "24.3".
Alternatively, it might make sense to completely drop the recipe, because el-get doesn't support Emacs versions before 24.3 anymore.
