'stand.h' file not found - but exists

i'm trying to build an image for Pine64 using a master checkout of crochet (61b57f3ecca9ca8781a9e1e23777de3076f4ade4) with the following config.sh::

board_setup Pine64
option Growfs
option GzipImage
option User admin
FREEBSD_SRC=/data/crochet/src/head
FREEBSD_INSTALL_WORLD=y

and /data/crochet/src/head containing:

root@crochet:/data/src/head # svnlite info

but when I search for stand.h I find this:

/usr/include/stand.h
/usr/jails/basejail/usr/include/stand.h
/usr/src/lib/libstand/stand.h

what am i missing here?

freebsd / crochet
