Best method for adding GeoIP support

[TheBritishGeek]

We have just started to work with Nginx and have installed by adding the
nginx repositry to our debian 7 installs. It works almost perfectly out of
the box as such. However we need to add GeoIP support, so the question is
what is the best method of doing this.  I really don't want to compile our
own install and break the simple apt-get upgrade path in the future if we
have a choice.  

Any advice would be greatly appreciated.
