No.  The problem is that you compiled ipfw2.c with the header
/usr/include/netinet/ip_fw.h, and not /usr/src/netinet/ip_fw.h.

The way you get the new header is to install it, and as you
noticed, that doesn't work.

Alternately, you can specify a CFLAGS=-I/usr/src, and it will
get the header that matches your kernel.

Since the buildworld is a simple fix (back out the changes to
the .mk file before trying to build), you should do that, instead.
