GRASS includes and uses a modified version of the PROJ library. These
symbols are present in the modified version, but not in the standard
version. Unfortunately, the Mac's linker uses the installed version in
preference to that included with GRASS.

Two alternative approaches:

1. Remove, rename or move the dynamic PROJ library (probably
libproj.dylib) which is installed on the system, so that it can't be
found when building GRASS. You can put it back afterwards.

2. In src/CMD/generic/make.mid, change the lines:

	DEPGPROJLIB    = $(LIBDIR)/libproj.a
	GPROJLIB       = -lproj
to:
	DEPGPROJLIB    = $(LIBDIR)/libgproj.a
	GPROJLIB       = -lgproj $(PROJLIB)
