Let me explain myself. If you compile a C program that has this line:
#include <linux/rtnetlink> in most default configurations gcc is going
to look at /usr/include/linux/rtnetlink.

Nowadays most distributions release a set of 'kernel headers' which are
stable enough, and put into /usr/include. These headers need not match you
current running kernel (All this is a little confusing for some people. In
fact, userspace applications should not include kernel header files but,
unfortunately, some userspace applications need to...

In your case, you may have on one hand your mpls patched kernel and on the
other one a set of kernel headers that have never heard of MPLS. Zebra
looks at them..

A fast workaround would be to modify zebra Makefile so it looks at the
MPLS enabled kernel headers first (something like -I/path/to/mpls/kernel)
do this at your own risk...

Sure, because the kernel headers found in /usr/include are enough for
zebra..
