The only extra files you need is a binary db(geoipdb.bin)& its index file(geoipdb.idx).
Take a look at http://people.netfilter.org/peejix/geoip/howto/geoip-HOWTO.html
for a quick HOWTO.

root@viaweb:/usr/local/src/csv2bin:# /bin/cp -r csv2bin /var/geoip/
root@viaweb:/usr/local/src/csv2bin:# cd /var/geoip/
root@viaweb:/var/geoip:#
wget http://attic-distfiles.pld-linux.org/by-md5/4/e/4e22dd36f85737f45f8595d0ba1f2e85/GeoIPCountryCSV.zip
root@viaweb:/var/geoip:# unzip GeoIPCountryCSV.zip
root@viaweb:/var/geoip:# ./csv2bin GeoIPCountryWhois.csv
root@viaweb:/var/geoip:# cp geoipdb.*/var/geoip/
7. GeoIP 설치 후 iptables 연동 확인
