It seems you copied libjq and libonig into usr/local/lib in the chroot. By default, ld.so only looks for shared objects in /usr/lib, so it can't find them. # env LD_LIBRARY_PATH=/usr/lib:/usr/local/lib chroot /var/www /usr/local/bin/jq --version should work. Chrooting to / works because rc(8) runs ldconfig(8) to add /usr/local/lib and /usr/X11R6/lib if they're present. You can copy all the libraries into /var/www/usr/lib, you can set LD_LIBRARY_PATH=/usr/local/lib:/usr/, or you can run ldconfig in the chroot. Read ld.so(1) and ldconfig(8) for more details.
