OK, I understand now. Yes, I have more options to the ./configure
./configure \ --enable-debug \ --enable-syslog \ --enable-local \ --enable-crypt \ --enable-spasswd \ --enable-modules \ --enable-backends=mod \ --enable-overlays=mod \ --with-cyrus-sasl \ --with-tls=openssl \ --prefix=/opt/openldap-2.5.5
With openldap-2.4.55 it did not require --enable-wt=no, and it threw me a little when I saw the default should be no. I've noted the new requirement, and have updated my documentation.
Sorry for my confusion, and thank you for your time.
