Either way works, the one you choose depends a lot on how you do things.

If your hosts are all the same OS but the guests are different then do
it the way you describe - it is consistent no matter what type of guest
you have.

If it's the other way round - different host OSes and all the guests are
Gentoo, the using portage makes more sense.

And, if you live and work in the real world, with many different
hypervisors on many different host OSes running many different guest
OSes with versions all over the place - then your life gets real
interesting real quick. (Don't ask how stuff got like that at work,
please please I beg you, do not ask. The pain, it is too much)

Still not my question... sorry for the unduly doopy forumutation.

I know guest-additions gets installed into a vbox vm once installed.

Until this go around and I've done quite a few installs of gentoo into
vbox vms ... but always installed the guest addtions that are already
present in the vbox package.  Not from portage as my host is win-10.

That is, click the devices menu at the top of the vbox screen and
click `install guest addtions'.  Go  to /media/cdrom and install them
with ./NAME_addtions.run.

I never installed them from portage... and had no idea they were even
available on portage.

Now if you are using the portage VBox package and installing vms on a
gentoo host, then it makes sense to get the guest-additions on
portage.

Well, I have to concur with what I did not prune out of this thread.
My recent experience with xf86* on my amd64 and the 3.18.6 kernel
had me reading quite a few horror stories of others; finally I 
found a solution, that is more a result of marathonic efforts
as opposed to finding the correct nuggets of information.

I.E. in this area I'm willing to bet there are ample bugs
and things that have been modified or fixed, but the knowledge
is just not disseminated. I filed no bugs because clarity
never appeared as to the exact problem(s).

For example in /lib/firmware/radeon I have these relevant drivers
some are lower case some are uppercase and my card requires the (V|v)erde*
drivers and at least one TAHITI driver. In fact the inter
relationships on some kernel options are there, but are not, or
are poorly, defined. I think this is a result of the quickened
turn_around speed of the kernel versions. Quality was sacrificed,
imho.

I found no documentation as to why. It's just a mess, imho. I could
list dozens of things, but the impression I got was (dev)folks are
hacking at this, but it's not cleaned up because there is little
clarity for (kernel) devs or other subsequent development efforts. 
I sure hope I'm wrong. ymmv.

For reasons I don't know, the gentoo devs split the guest-additions
into two parts: they put the vboxvideo kernel module into the gentoo
xf86-video-virtualbox package, and the vboxguest+vboxsf kernel modules
into the virtualbox-guest-additions package.

Anyway, starting with a vbox gentoo snapshot from Mar 3 (before the
update to vbox-4.3.24) I upgraded only the virtualbox-guest-additions
(not the xf86-video-virtualbox package) and found that everything still
works normally.

I then upgraded the xf86-video-virtualbox package and discovered that
3D video acceleration was broken, just as before.

I then downgraded the xf86-video-virtualbox package to 4.3.20 (leaving
the virtualbox-guest-additions at 4.3.24) and found the 3D acceleration
working normally again.

That clearly implicates the vboxvideo.ko kernel module as the cause of
the breakage, I think.

Opinions/comments are most welcome.
