Then you should get in touch with the person who added that definition,
and ask him to add it to the bsd.pkg.defaults.mk.

cvs annotate tells me:

1.26         (kleink   04-Oct-00): .if defined(USE_LDAP) && ${USE_LDAP} == YES
1.26         (kleink   04-Oct-00): WITH_LDAP=   --with-ldap=yes
1.36         (kleink   26-Oct-01): DEPENDS+=    openldap-[0-9]*:../../databases/openldap
1.26         (kleink   04-Oct-00): .else
1.26         (kleink   04-Oct-00): WITH_LDAP=   --with-ldap=no
1.26         (kleink   04-Oct-00): .endif
1.26         (kleink   04-Oct-00):

and cvs log tells me:

----------------------------
revision 1.26
date: 2000/10/04 12:55:14;  author: kleink;  state: Exp;  lines: +11 -3
Be deterministic about providing LDAP support.
----------------------------

So thanks for pointing it out - since bsd.pkg.defaults.mk is .include'd
to set all the defaults, it would be even more necessary to includean
explanation and a default value in bsd.pkg.defaults.mk.
