As I said, if you did not already have apr-util installed, no special
action would have been necessary. Installing apache2 +openldap would
have caused apr-util +openldap to have been installed automatically.
The problem only arose because you already had apr-util installed
without +openldap.
Our documentation is out of date for most things, not just this. We
are attempting to work on the documentation again. Specific
suggestions for where in the documentation this should go and/or what
specifically should be said would be helpful. I say this because I'm
not sure what it should say to avoid being both overly wordy and
overly specific. (If it said "If you want to install apache2
+openldap but already have apr-util installed without +openldap,
uninstall apr-util and reinstall it with +openldap" that would be way
too specific to that port. If it said "If you want to install a port
that depends on a particular variant of another port but you already
have a different variant of that other port installed, then you will
need to uninstall that other port and reinstall it with the variants
required for the new port you want to install" then that would be
overly wordy, and probably nobody reading that would in fact
recognize the problem when they encounter it.)
Perhaps a better solution is to update the apache2 portfile, in this
case, so that if you select +openldap, it checks apr-util to see if
it's installed with +openldap, and if not, it prints an error that's
slightly friendlier than the one that apache2 printed for you. (I say
slightly friendlier because the message it printed was already pretty
friendly: it already pretty much told you what you needed to do to
correct the problem.)
