LDAP server unreachable

[Rhys Johnson <rj1@westnet.com.au>]

hello all
I am getting this error when I try and start slapd. 
Nov 11 09:59:06 bogey slapd[11675]: daemon: socket() failed errno=97
(Address family not supported by protocol)

The daemon starts ok but I cant view my ldap database from evolution.
This only became a problem since I upgraded from woody to sarge. All 
configuration settings remain the same. When trying to access my ldap
database, Evolution says:
We were unable to open this addressbook.  This either
means you have entered an incorrect URI, or the LDAP server
is unreachable.

I am running Debian unstable linux using slapd (2.1.30-3) and evolution
(1.4.6-5)

Here is my slapd.conf
