I wrote about MesaLib in this mailing list and/or tech-pkg a bit earlier,
although it was on NetBSD 7, not on 8. So my solution might not work for you.
See "Inverted OPSYS conditional in graphics/MesaLib/options.mk" in
tech-pkg starting 15 april:
http://mail-index.netbsd.org/tech-pkg/2018/04/15/msg019669.html
On 7, there is no dri3 so I manually disabled that in options.mk. dri
(not 3) was ok.

I also had problems with *some* users of libGL that had link errors
(table_noop_array undefined). For that I adopted a bunch of patches from
wip/MesaLib. See
http://mail-index.netbsd.org/tech-pkg/2018/04/17/msg019677.html
http://mail-index.netbsd.org/pkgsrc-users/2018/04/22/msg026524.html
I don't know if pkgsrc has a fix included now, or if it isn't relevant
in 8.
I learned that it is important that all openGL related libraries are
from the same source, since otherwise some programs get linked to
multiple versions of the same library (base and pkgsrc).
So I have in my /etc/mk.conf
PREFER.libdrm = pkgsrc # req'd by MesaLib
PREFER.MesaLib = pkgsrc
PREFER.glu = ${PREFER.MesaLib} # automatically correct for most; req'd
for xscreensaver
PREFER.gle = ${PREFER.MesaLib} # req'd by xscreensaver
# GL, gle and glu should generally match up, PREFER-wise.
I also build everything with gcc 4.9 (not default on NetBSD 7) but since
8 has an even newer version, that won't be a problem I expect.
Note that if you change any of this after you already built some
packages, you may need to rebuild some! In particular x11-links is
sensitive to this.
