The extra files you will need is the binary database files. They are generated
from a country-subnet database with the geoip_csv_iv0.pl tool, available at
http://jengelh.hopto.org/files/geoip/ . The files MUST be moved to /var/geoip/
as the shared library is statically looking for this pathname (e.g.
/var/geoip/LE/de.iv0).
