While trying to build $subj on 10.2, I noticed an oddity in the
Makefile:

        cd ${WRKSRC} && ${SH} env.sh && \
            ${KMK_CONFIG} ${LOCALBASE}/bin/kmk ${KMK_FLAGS}

the last two lines are wrong - env.sh sets environment variables and
needs to be sourced into the shell before kmk is invoked, like
virtualbox-ose des:

        cd ${WRKSRC} && \
            ${SH} -c '. env.sh && ${KMK_CONFIG} ${LOCALBASE}/bin/kmk 
${KMK_FLAGS}'

although I don't think it will fix the problem, which is that kmk just
hangs on wait channel umtxn.  I changed the Makefile so it reads:

        cd ${WRKSRC} && (. env.sh && ktrace -di env \
            ${KMK_CONFIG} ${LOCALBASE}/bin/kmk ${KMK_FLAGS})

"make build" now shows:

It ignores the SIGINT and remains stuck in the backgrounf until I
SIGKILL it (pkill -9 kmk).
