This is exactly what ALL-DEPENDS-LIST does. Except it's faster. It
keeps two lists and generates a third implictly, with a two more
temporary lists... The first is $$L, which start cas _DEPEND_DIRS. It
loops over L and for each directory ($$d) in $$L checks if it has
already been there (the ports dependencies are not a single list - a
port like gnome2 implicitly depends on libtool hundreds of times), and
skips it if it has, otherwise it adds it to $$checked, which is the list
of directories it has checked, and echo's it so it is added to the
result of ALL-DEPENDS-LIST. It then does a make -V _DEPENDS_DIR in the
directory (getting $$children), which it then checks to make sure they
are not in the list of checked directories or directories to be checked.
If they are not it adds them to $$l, the list of directories to check.
Once it has done with the directories in $$L it sets $$L to $$l, and
starts over, until there are no more directories.
Regards,
