Link stage of libip6t_NETMAP failed since recently.
CCLD libip6t_NETMAP.so
/usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld:
cannot find -lip6tc
libip6t_NETMAP.c uses the "ipv6_prefix_length" function from
libip6tc.so; "-lip6tc" is used in the Makefile, but, the directory to
it is not specified.
Why does the link succeed for some people? Because
/usr/lib(64)/libip6tc.so satisfies -lip6tc, but not all environments,
especially those without iptables development files, have that file,
hence this link error can happen.
