recursive 'make config'?

You can't do a recursive make config like that I'm afraid.  What you
can do is set the various configuration options used by make(1) before
starting the compilation job, so that it doesn't stop to ask questions
halfway through.  There's actually quite a number of ways you can do
that:

    i) Globally in /etc/make.conf -- variables set here will apply to
       all ports you compile.

   ii) Setting the variable in the environment before starting the
       compilation.  Again this applies to all compilations, but only
       certain variables can be set this way.  Many will be overridden
       by settings in Makefiles or make.conf.

  iii) Globally in the 'Environment' section of
       /usr/local/etc/pkgtools.conf -- of course this only works if
       you're a portupgrade(1) user.  Same caveats as for (ii) apply

   iv) Locally to a port by creating a Makefile.local in the port
       directory and putting the settings within that.  There are
       actually several subsiduary makefile names that will be
       automatically included like this: see /usr/ports/Mk/bsd.port/mk
       for details.  Note however that 'Makefile.local' is the name
       intended for human overrides of the default settings, whereas
       'Makefile.inc' and '../Makefile.inc' can be machine generated
       as part of the port's configuration, or it can be a permanent
       file commited as part of the ports.

    v) Locally to a port (or a series of ports matching a glob
       expression) in the MAKE_ARGS section of pkgtools.conf

   vi) Locally to a port if it uses the OPTIONS variable within it's
       Makefile.  In these cases, just run 'make config' one time, and
       the settings will be stored in /var/db/ports: you'll only get
       the configuration dialog coming up if the port is modified to
       use some new options.

Option vii) is (of course) to set the options on the make(1) command
line, as you build the port, which I include for completeness' sake
only as it doesn't help you run your big build job unattended.

Most people will use a combination of (i), (v) and (vi) -- for those
ports where it applies.  You will still have to scan through all of
the dependency ports that you will be installing, read their Makefiles
and decide what options (if any) you wish to set.  You can get some
lists of the dependencies by running:

    % make pretty-print-build-depends-list
    % make pretty-print-run-depends-list 

from the directory of the top level port you wish to install.
