he seems to be doing the right thing:
# add some OS X style app support paths, and create user one if missing.
mkdir -p "$GISBASE_USER/Modules/bin"
if [ "$GRASS_ADDON_PATH" ] ; then
i.e. if it exists add to it, otherwise start fresh.

right, GRASS_ADDON_PATH is an environment variable,
not a GRASS variable. It needs to be used before
grass starts up.

changes in the terminal are only seen in that
terminal and children of that terminal. one process
can't hijack the settings of another one. If you
had started the gui from that terminal with g.gui
I expect it could have worked. but you can't adjust
an already running process from another one.

it's the first dir on the list which gets used by

It has to be like that for a number of other things
too, GRASS_PYTHON for example... you may have had
it set in g.gisenv (you can put whatever you like
in there), but I can pretty much guarantee that it
won't have done anything.
if you 'export GRASS_ADDON_PATH=' from your .profile
it should be at the start of the list when you
type "echo $GRASS_ADDON_PATH" in the grass terminal,
followed by the ones that William added. (this
isn't an old migrated Mac user account using csh
instead of bash, right?)
If it's not, sorry I don't have a mac handy to test
on, it's probably just a simple miscommunication
