Apache2 +openldap error

[Samuel V.Green III]

Upon issuing a sudo port installed I get:

apr-util @1.2.8_2 (active)
......,
openldap @2.3.35_0 (active)
.....,


Upon issuing sudo port install apache2 + openldap I get :

error: #error mod_authnz_ldap requires APR-util to have LDAP support  
built in. To fix add --with-ldap to ./configure

Reading this I recognized that I DID NOT build the APR-util with the  
+openldap option.
I then did an uninstall of apache2 as well as php5 to correct this  
error.
I'm now trying again to get Apache2 to build with openldap.

Can someone point me to the documentation in the MacPorts Wiki or  
whatever that would have
prevented me from "the long route?"
