The next release will have this in the manual page:

       If your kernel does not support rtnetlink (routing messages),
       you will get a warning of the form
              traceroute: Warning: findsaddr: error sending netlink message: <reason>
              traceroute: Warning: ip checksums disabled
       This is harmless as IP checksums will be provided by the kernel,
       and UDP  checksums  (which are also disabled when rtnetlink is
       unavailable) are optional.
