Created attachment 157799 [details, diff] ip_tunnel.h patch It's the 'new' include/ structure that differs from the files in /usr/include; include/linux/ip_tunnel.h doesn't include asm/byteorder.h, which eventually defines __constant_htons. This patch makes the minor change necessary, but may not be all that's eventually needed if iproute2 continues to carry around its own headers.
should be fixed in cvs now http://sources.gentoo.org/sys-apps/iproute2/iproute2-2.6.25.20080417.ebuild?r1=1.1&r2=1.2
