#73991: grass assumes symbols in OpenGL which may not exist, which breaks the build
--------------------------+--------------------
 Reporter:  barracuda156  |      Owner:  (none)
     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.12.5
 Keywords:                |       Port:  grass
--------------------------+--------------------
 These symbols do not exist in GL 2.x, I guess, so it should be configured
 to use `mesa` on systems without GL 3.x.
