Mac support is much needed!

Maybe this changeset from last night is helpful for you:

I just get awful black and white triangles, irrespective of what I use: 2D data or 3D data resulting from the extrusion of 2D. I’ve done tons of trials, used ST_Extrude in PostGIS/SFCGAL to get polyhedrons, etc. No dice.

.. perhaps better discussed on the grass-dev mailing list.

So let's try to get that working also on Mac :)
