...failed since around November 15 or so.

The facts:
    - userland is -current as of November 15, kernel is -current from src
      updatated an hour ago.
    - /usr/src is a symlink to /u/NetBSD/src
    - /usr/src is union mounted to /u/NetBSD/lsrc
      (/u/NetBSD/lsrc          /usr/src        union   rw,noauto 0 0)

    - I call /usr/src/build.sh like this:
      ./build.sh -O /u/NetBSD/arch/i386/obj -D / -T /u/NetBSD/arch/i386/TOOLS

    - There's no /etc/mk.conf, /u/NetBSD/arch/i386/obj is empty

I've done "make install" in /usr/src/share/mk but still get this:

(cd /u/NetBSD/src/tools && /u/NetBSD/arch/i386/TOOLS/bin/nbmake dependall)
dependall ===> host-mkdep
install ===> host-mkdep
dependall ===> compat
nbmake: don't know how to make fgetln.c. Stop

nbmake: stopped in /u/NetBSD/src/tools/compat
*** Error code 2

So has anyone an idea where the culprit is? 

Thanks,
