Thanks Paul,

Now on first attempt from virgin git using "make deb" we're back to:

-----

In file included from /usr/src/libreswan/programs/pluto/linux-copy/linux/xfrm.h:5:0,
                 from /usr/src/libreswan/programs/pluto/kernel_netlink.c:56:
/usr/include/netinet/in.h:101:5: error: expected identifier before numeric constant
     IPPROTO_HOPOPTS = 0,   /* IPv6 Hop-by-Hop options.  */
     ^

So again used:

echo USE_XFRM_HEADER_COPY=false >> Makefile.inc.local

and end up halted at:

                 from /usr/src/libreswan/programs/pluto/kernel_netlink.c:56:

     IPPROTO_HOPOPTS = 0,   /* IPv6 Hop-by-Hop options.  */
