Steps to install:

Installation of BIND 9.4.3-P1 with geodns patch
--------------------------------------------

This document explains how to install BIND the geodns patch.  We will use /usr/local/src/ to unpack source code and /usr/local/bind as installation directory for BIND.

1) Download BIND 9.4.3-P1 from http://www.isc.org/sw/bind/
2) Download GeoIP C API from http://www.maxmind.com/app/c
	wget http://geolite.maxmind.com/download/geoip/api/c/GeoIP.tar.gz
3) Unpack both in /usr/local/src/
	(geoip needs to be unpacked into a directory called "geoip" for the below commands to work)
4) Compile GeoIP and install in /usr/local/geoip/:
	./configure --prefix=/usr/local/geoip
	make
	make install
5) Download the city data http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
	wget http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
6) Extract city data to /usr/local/share/GeoIP, and rename to GeoIP.dat
7) Patch and install bind:
	cd /usr/local/src/
	patch -p0 < bind-9.4.2-P1-geodns-patch.diff 
	cd bind-9.4.3-P1
	CFLAGS="-g -O2 -I/usr/local/geoip/include" LDFLAGS="-L/usr/local/geoip/lib -lGeoIP" ./configure --prefix=/usr/local/bind
	make && make install

Make an init script, config files, etc, start named, and voila.
