How to make a make install without questions?

[TooMany Secrets]

Hi!

Excuse me if this is a estupid question, but in six years with
FreeBSD, today I haven't still an answer to this:
- If I make a "make install clean", in a port like "x11/kde3", are
there any way to make the lack of questions? Or maybe better, are
there any way to make anything like "make -y (or -Y for YES options)
install clean"?

The trouble is ports like KDE, with platform independency (more or
less cpu power), take more time because you need to stay (more or
less) in front of computer to choose and accept the port options.
I understand that you don't need this with other ports (like apache,
php, etc), for obvious reasons. But I think that with ports like
gnome2 or kde3, maybe I believe that it would be a great saving of
time.

Sorry if the question is understandable for my bad english.
