I don't know how to fix this because the #version directive was not modified at all.

  Hi,
  I have installed povray 3.7 from the Ubuntu repos, using the standard software
manager Synaptics. The optics.pov (and all demo scene files) are from this
installation.
  I did not know that there is qtpovray-includes and qtpovray-extras. I have not
installed this packages. I will install these after posting this writing.
  The installation of qtpovray installed a folder with *.inc files in:
/usr/share/qtpovray-3.8/include, so it is using that
folder.

  I'm using an very old 1-core cpu AMD Sempron LE-1150 2.0 Ghz without AVX,AVX2,FMA3
support *but* with SSE2 instructions. I don't know why these was not detected.

I think that the "macro" declaration in line 167 needs a "#version" > 3.1 but the
"detected" version is 3.0. Resolving
the version issue will resolve the macro issue. (I'm guessing)
