FreeBSD ports: question about apache and mod_ldap

Hi.

I made the mistake of upgrading my apache22 configuration on my FreeBSD
6.3 machine.

Now, for some reasons, mod_authz_ldap and mod_ldap aren't compiled .

my make.conf file contain the following:
WITH_LDAP_MODULES=yes
WITH_AUTHZ_MODULES=yes
WANT_OPENLDAP_VER= 24

in /usr/ports/www/apache22 I run make as I always do...
showing everything relevant to ldap:

configure shows:
checking for ldap support...
setting APRUTIL_INCLUDES to "-I/usr/local/include"
setting APRUTIL_LDFLAGS to "-L/usr/local/lib"
checking for ldap_init in -lldap50... no
checking for ldap_init in -lldapssl41... no
checking for ldap_init in -lldapssl40... no
checking for ldap_init in -lldapssl30... no
checking for ldap_init in -lldapssl20... no
checking for ldap_init in -lldapsdk... no
checking for ldap_init in -lldapsdk... no
checking for ldap_init in -lldap... yes
setting APRUTIL_EXPORT_LIBS to "-lldap -llber"
setting APRUTIL_LIBS to "-lldap -llber"
checking for ldapssl_client_init in -lldap... no

checking for ldapssl_add_trusted_cert in -lldap... no
checking for ldap_start_tls_s in -lldap... yes
checking for ldap_sslinit in -lldap... no
checking for ldapssl_init in -lldap... no
checking for ldapssl_install_routines in -lldap... no
....
checking for ldap.h... yes
checking ldap_ssl.h usability... no
checking ldap_ssl.h presence... no
checking for ldap_ssl.h... no
checking for LDAP toolkit... OpenLDAP
....
hecking whether to enable mod_authz_dbm... shared
checking whether to enable mod_authz_owner... shared
checking whether to enable mod_authnz_ldap... no
checking whether to enable mod_authz_default... shared
...
checking whether to enable mod_ldap... no

And of course the file mod_ldap.so and mod_authnz_ldap.so do not exist
in /usr/local/libexec/apache22.

openldap24-client is installed.
I also tried with openldap23-client installed, just the same...

Any ideas ? has anything changed lately in the FreeBSD ports that
changes the way apache22 needs to be configured to build the ldap
module support?

Thank you in advance.
