Note: Your environment is not up to date enough to be using
python38 . The log shows:

[  1% 4/69] /usr/local/bin/python3.7  . . .
. . .

I'll note that /usr/ports/UPDATING reports:

  AFFECTS: users of python
  AUTHOR: kai at

  The default version of python3 and python was switched to 3.8.

  For ports users wanting to keep version 3.7 as default,
  add DEFAULT_VERSIONS+= python=3.7 python3=3.7 to make.conf

  Following procedures may ease the upgrade:

  For users of pre-build packages:
  # sh
  # for i in $(pkg query -g %n 'py37-*'); do pkg set -yn ${i}:py38-${i#py37-}; done
  # pkg upgrade

  For portmaster users:
  # sh
  # portmaster -o lang/python38 python37
  # REINSTALL="$(pkg info -o "*py37*" | awk '{printf "%s ", $2}')"
  # pkg delete -f "*py37*"
  # portmaster $REINSTALL
  # REBUILD=$(pkg query -g "%n:%dn" '*' | grep py3 | grep -v py38 | cut -d : -f 1 | sort -u)
  # portmaster $REBUILD
  # REBUILD2=$(pkg list | grep python-37 | xargs pkg which | awk '{print $6}' | sort -u)
  # portmaster $REBUILD2

The log also shows the use of -Xclang in the cc commands:

cc -Ijson-glib/ . . . -Xclang -fno-color-diagnostics . . .


does not show any use of -Xclang .

-Xclang makes the following argument be passed directly to the
cc1 compiler stage. So the:

error: unknown argument: '-fno-color-diagnostics'

would be from cc1. "clang -cc1 --help" only reports one
form of color-diagnostics option allowed by the -cc1

  -fcolor-diagnostics     Enable colors in diagnostics

Viewed various ways that confirm:

# more main.c
static volatile char big_area[67001] = "This is a test";
int main ()
    big_area[67000] = '9';

# clang -Xclang -fno-color-diagnostics main.c
error: unknown argument: '-fno-color-diagnostics'

But the detail of what is involved, showing the
-cc1 command that is internally generated, is:

# clang -### -Xclang -fno-color-diagnostics main.c

Another way:

# clang -cc1 -fno-color-diagnostics
error: unknown argument: '-fno-color-diagnostics'

So the question becomes how -Xclang got involved.
I do not know yet. It is not explicit in the
Makefile . It is not obvious where to look.

I should not have included "-DBATCH" in my wording. So:

is incoherent: the first says not to do the last.
