FWIW, a couple of weeks ago, I started (also) tracking stable/9 daily
with the following in /etc/src.conf:

PORTS_MODULES=x11/nvidia-driver
CC=clang
CXX=clang++
CPP=clang-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"
...
    Screen          0
    Option         "UseEdidDpi" "False"         # [<bool>]
EndSection
...
Section "Monitor"
...
    DisplaySize     508    317
EndSection
....

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
