I can confirm that this patch did work for me, with the use of Homebrew-provided PNG and JPEG libraries. I also had to provide Xerces-c to get GML working, and used the same *_PATH env vars.

Hm — this hasn’t exactly been my experience. I have found that without external libraries installed and without CPLUS_INCLUDE_PATH and LIBRARY_PATH defined, the compile process complains about missing *.h header files for JPEG and PNG. I have also tried a bare ./configure without any special env vars, and it halts here:

	checking for json_object_set_serializer in -ljson-c... yes
	using pre-installed libjson-c
	configure: error: could not find json-c/json.h
