You can use the command

	# make missing

to get a list of which dependencies need to be installed.
See "man 7 ports" for other targets that might be useful.

Correct. Dependencies are resolved and installed (usually
by compiling them from source, installing and registering
them), then the initial build is returned to.

If the default options of the dependency ports are fine for
you, this should be no problem.

Change CWD to the location of the packages (on CD) and
try again. According to "man pkg_add":

	If the packages are not found in the current
	working directory, pkg_add will search them in
	each directory named by PKG_PATH.

If there's still an error, can you provide the command
you entered plus the output? Maybe adding -v helps to
give some more information.

The ports do not use pkg_add.

However, using a tool like portmaster or portinstall can
help you using binary packages (options -P and -PP).

If you use pkg_add -r, some "more magic" will be applied
to form the proper URI for fetching the packages (e. g.
architecture and OS version may be considered).

I don't remember any particular documentation regarding
this procedure. The pkg_add command should automatically
install dependencies (option -i to prevent).

I think that's possible; I hope you got some inspiration.
