graphviz @2.40.1: compile: unable to infer tagged configuration

Please see attached main.log, which I unfortunately couldn't make much sense of.

libtool is missing a tag to tell it what to do in the second line here, which fails (Objective-C):

:info:build /bin/sh ../../libtool  --tag=CC   --mode=compile /usr/bin/clang -std=gnu11 -DHAVE_CONFIG_H -I. -I../..  -I../.. -I../../lib/common -I../../lib/pathplan -I../../lib/gvc -I../../lib/cgraph -I../../lib/cdt  -I/opt/local/include -I/opt/local/include  -pipe -Os -arch x86_64 -Wall -Wextra -Wmissing-include-dirs -Wswitch-default -Wfloat-equal -Wundef -Wshadow -Wpointer-arith -Wbad-function-cast -Wcast-qual -Wconversion -Wstrict-prototypes -Wmissing-prototypes -Wnested-externs -fno-common -Wall -MT gvtextlayout_quartz.lo -MD -MP -MF .deps/gvtextlayout_quartz.Tpo -c -o gvtextlayout_quartz.lo gvtextlayout_quartz.c
:info:build /bin/sh ../../libtool             --mode=compile /usr/bin/clang            -DHAVE_CONFIG_H -I. -I../..  -I../.. -I../../lib/common -I../../lib/pathplan -I../../lib/gvc -I../../lib/cgraph -I../../lib/cdt  -I/opt/local/include -I/opt/local/include  -pipe -Os -arch x86_64 -MT GVTextLayout.lo -MD -MP -MF .deps/GVTextLayout.Tpo -c -o GVTextLayout.lo GVTextLayout.m

I don't know why it's missing a tag exactly, but it is and that is why it dies in this particular spot.

Here's some related internet wisdom that may or may not prove useful <​https://bugs.gentoo.org/630072>
