Makefile management of various OpenLDAP versions in FreeBSD ports (ITS#2637)

A method for more intelligent management of installing OpenLDAP (specifically
under
FreeBSD) is being considered as there are different applications which use
OpenLDAP,
but they may require different versions of OpenLDAP. Additionally, a user may
install
a source version of OpenLDAP, with or without many local configuration and/or
schema
changes, that could be severly impacted by the installation of another OpenLDAP
because of its inclusion in a FreeBSD (application) port. At the moment, each
usage of OpenLDAP, by the user or a port, is "handled" indepdendently and no
attention is
paid to the version of OpenLDAP involved with respect to other uses/requirements
of OpenLDAP.

In essence, a user or port may install OpenLDAP-2.1.22, but another port may
require OpenLDAP-2.0.15, or OpenLPAP-1.5.x, or whatever. The side affect of this
is the overlay of any previous installation of OpenLDAP and the possible
destruction of any previously existing database. Another side affect is the
specification of an earlier version of OpenLDAP which is not really required
when an existing installation, or available newer version, will provide the
necessary LDAP functionality.

In addition to better managing the requirements for various versions of OpenLDAP
is the intent, and desire, to allow the user to override the application
Makefile to prevent it from forcibly installing another version of OpenLDAP when
said user already knows that they have OpenLDAP installed. Then the question of
appropriate OpenLDAP VERSION is left up to the user to decide/verify, but this
also allows said user the ability to PREVENT the installation of OpenLDAP by a
(FreeBSD) application port (as mentioned below).

The general desire of this "problem report" is to better coordinate the
existance of OpenLDAP on a (*BSD) system and all applications which require AN
OpenLDAP installation (as a part of that BSD system's port/packages distribution
mechanism), as well as any user-installed source versions. One proposal is
stated below, and is hereby submitted for comment by OpenLDAP.org.

Maybe we need a bsd.ldap.mk file that works much the way the Java
version does.  If you want to draw up some patches that could be used
globally, I'll take a look.  You might also want to involve the OpenLDAP
maintainers to see what they would like to do.  We have so many OL
versions in the tree now, that there really does need to be a better way
of doing dependency handling.  I'm really not in favor of carving up
individual ports, though.
