make config-recursive for an individual port

[Gary Aitken]

I have most ports installed via packages.
But when I do a make config-recursive from the directory of an individual port,
it brings up the config dialogs of packages which are already installed.
In fact, it appears as if it is trying to configure the whole ports tree,
but of that I can't be sure; things like git, curl, bash-completion, etc.

Does this mean it is going to try to build those ports as well?
Does this mean it will try to install them when I do a make install?
If not, why are they being configured in the first place?

Now a bit apprehensive...
