Can Gnome install from CD-ROM with defaults?

[knowtree at aloha.com]

I want to install Gnome in a classroom situation, either live or as a
homework project. I prefer not requiring the bandwidth a network install
entails. This step will follow installing FreeBSD, so it will be on a clean
machine.

Is there a way to do this using CD-ROM? 

What if I did it once ahead of time, then copied all the tarballs to the
new machine's /usr/ports/distfiles, then ran the gnome2 installer? Would
that work without a network connection?

Is there a way to run the installer with the option to take all defaults
and not prompt? I recall having my recent installs get stuck several times
waiting for me to accept the proposed configuration for this or that port.

Mahalo!
