I built an entire system, from scratch, with:

    PATH=/usr/tools/bin:$PATH ./build.sh -D /usr/netbsd \
        -O /usr/obj \
        -T /usr/tools \
        distribution kernel=CHALLENGER

MKX11 was set to YES in my /etc/mk.conf

I moved my old /usr/X11R6 out of the way and did

    PATH=/usr/tools/bin:$PATH ./build.sh -D /usr/netbsd -T /usr/tools install=/

But /usr/X11R6/lib/X11/rgb.txt wasn't created.  Should it have been?  
Or did I do something wrong in my build or installation?
