gwhich @2.20 build failure

[swinbank@…]

The relevant extract from the log is:

:info:build source='getopt1.c' object='getopt1.o' libtool=no \
:info:build 	DEPDIR=.deps depmode=none /bin/sh ./depcomp \
:info:build 	/usr/bin/clang -DHAVE_CONFIG_H -I.   -I/opt/local/include  -pipe -O2 -arch x86_64 -c getopt1.c
:info:build Unknown depmode none
:info:build Unknown depmode none
:info:build make[2]: *** [getopt1.o] Error 1

(Full log attached for reference).

I can build an (apparently) working version by adding --disable-dependency-tracking to configure.args, although I'm not sure I fully understand the implications of this. Patch attached.
