I'm trying to build netbsd 'current', but seem to be missing some files...

build.sh contains a 'getmakevar' function that contains:
        $make -m ${TOP}/share/mk -s -f- _x_ <<EOF
TOP seems to be defined as:
    TOP=`pwd`

However there is no 'share' directory in the one that contains
build.sh.

Indeed "find / -name share" only prints /usr/share, and that one
contains definitions for 1.5.2, not current.

I obtained the source tree from 'anoncvs' following the info in
the 'Tracking netBSD Current' document.
(rather than downloading one of the 'tar' files).

The documentation isn't quite right though:
    cvs checkout -P src
didn't give the kernel sources, which I got separately by:
    cvs checkout -P syssrc
I also fetchd the gnu stuff with:
    cvs checkout -P gnusrc

These definitely need merging together - may give problems with
cvs update, especially in usr.sbin.

What have I missed, done wrong, ... ?
