there must be something wrong in your build tree or src tree.
i updated and built this from a clean tree fine.

this should have been fixed with this pullup:

revision 1.175.2.1
date: 2023-09-04 10:33:28 -0700;  author: martin;  state: Exp;  lines: +3 -1;  commitid: 2TUS7rO7f7zuGtDE;
Pull up following revision(s) (requested by riastradh in ticket #343):

to etc/mtree/special.  try making sure this is properly updated,
and perhaps clean the objdir for etc/mtree and/or the destdir
entirely.
