FWIW, a couple of weeks ago, I started (also) tracking stable/9 daily
with the following in /etc/src.conf:
PORTS_MODULES=3Dx11/nvidia-driver
CC=3Dclang
CXX=3Dclang++
CPP=3Dclang-cpp
Given that, as well as the following excerpt from this morning's
typescript from the build:

I believe I am actually building with clang (on that slice -- I
build it with gcc on the other slices).
I did find that whether I use gcc or clang, I needed to modify xorg.conf
to say:
Section "Device"
=2E..
Screen 0
Option "UseEdidDpi" "False" # [<bool>]
EndSection
=2E..
Section "Monitor"
=2E..
DisplaySize 508 317
EndSection
=2E...
to get the font size I had when I was using the nv driver (and to which
I had become accustomed).
As shown above, though, I'm running FreeBSD/i386.
Peace,
david
