ll_recover_lost_found_objs was added to the lustre tools (namely lustre-$version rpm) in 1.6.6 (see bug 15284). So you can either install the lustre userspace tool rpm provided with 1.6.6 or 1.6.7 or just extract the binary from the rpm with rpm2cpio. There is no problem to use ll_recover_lost_found_objs with 1.6.5.
