ldap installation problem with apache

[Umar Draz]

Hi,

I am trying to install apache-2.2.1 on FreeBSD 8.2 64bit, I want to use ldap_authentication. Here is my make.conf

WITH_LDAP_MODULES=yes


But I am getting this error on make install


mod_authnz_ldap.c:41:2: error: #error mod_authnz_ldap requires APR-util to have LDAP support built in. To fix add --with-ldap to ./configure.
mod_authnz_ldap.c:63: error: expected specifier-qualifier-list before 'deref_options'


the apr package is also installed

apr-0.9.19.0.9.19_1 Apache Portability Library


Please help me how to solve this error

Best Regards,

Umar
