Personally, I couldn't anymore handle the way ports asks for configuration optio...

    echo BATCH=1 >>/etc/make.conf

No more prompts for options - they should all certainly have sane defaults. If not, it's a good reason to run send-pr.

I've always been a fan of

    make config-recursive && make install clean

which runs `make config` on the package and all dependencies before installing. It's the best of both worlds IMO -- the port will build unattended and you still have a chance up-front to skim the available options for things you need.

Also

  make -DBATCH install clean

in port directory will do unattended build with default settings. It affects current port and all of its dependencies.

Either set BATCH env variable or use portupgrade/portinstall with -c or -C flags. The latter gathers all the dependencies of a given port and let's you configure them up front, and then the compilation and installation goes without any interruptions.

    -c 
    --config
     	 Run "make config-conditional" before everything for all tasks.
    -C 
    --force-config
     	 Run "make config" before everything for all tasks.
