the problem is read-only src and the make distribution phase:

Build finished at: Tue Jun  6 13:07:39 EST 2006

EV.awk /usr/src/etc/MAKEDEV.tmpl > /usr/src/etc/MAKEDEV
cannot create /usr/src/etc/MAKEDEV: read-only file system

-It looks like the build.sh process isn't setting an OBJDIR derived
path for an output event...
