Could you provide some more context? Ideally everything after the
prior "Entering directory ..." line, to indicate which component is
being built and the command which is generate the errors.

In which case, GRASS ought to skip any component which requires
OpenGL.

I suspect that this arises from building the Python ctypes wrappers
for the OGSF and NVIZ libraries.

In which case, we should probably change the definition of MODULES in
lib/python/ctypes/Makefile to e.g.:

	MODULES = date gis raster gmath proj imagery vector rtree display stats \
		dbmi raster3d arraystats cluster vedit segment rowio temporal
	ifneq ($(USE_OPENGL),)
	MODULES += ogsf nviz 
	endif
