Milter-greylist

I am seeing lots of the following in my logs:
milter-greylist: GeoIP is not available

However, I know that GeoIP is installed:
[root@host ~]# rpm -qa | grep -i geo
perl-Geography-Countries-1.4-2.2.el5.rf
GeoIP-devel-1.4.3-1
GeoIP-1.4.3-1

[root@thor ~]# /usr/bin/geoiplookup milter-greylist.sf.net
GeoIP Country Edition: US, United States
[root@thor ~]#

I had rebuilt the milger-greylist from src, pointed it to the
libraries... and it indicated it found them.
I am currently running "milter-greylist-4.0rc1"
