compile of Apache 2.2-3 fails with LDAP modules enabled

[qmtpeters]

I have a Red Hat linux machine with OpenLDAP 2.3.25 loaded on it. I
tried to configure/make Apache 2.2.3 with the following configure
options:

configure --with-ldap
--with-ldap-include=/local/mnt/openldap-2.3.25/include
--with-ldap-lib=/local/mnt/openldap-2.3.25/libraries/libldap
--enable-authnz-ldap --enable-ldap

The configure succeeded, the 'make' failed with the following errors:

modules/ldap/.libs/libmod_ldap.a(util_ldap.o) (.text+0x217): In
function 'uldap_connection_open':
/usr/local/httpd-2.2.3/modules/ldap/util_ldap.c:243: undefined
reference to 'apr_ldap_init'

....as well as 10+ other errors simular to the one above, all from
util_ldap.c

Any help here would be greatly appreciated!

Apache version 2.2.3
