The Persistence of Vision Raytracer source tarball.
This release of POVRay is intended for building on Linux or Apple Sierra OS. It fixes a couple compile time obstructions. It does not require MacPorts (but Apple X-Code is required of course). On mac it will have image output but no gui pop-up window.
Please see http://www.povray.org for other/official releases.
To build do the iconic:
# ./configure
# make
# make install
