Erich, can you, please, send me the full output and the exact setup you used? I suspect you may be using XQuartz 2.8.0 or higher which has broken pkg-config files - latest XQuartz requires a patch to make any compilation against it work (see https://github.com/R-macos/recipes/blob/master/other/tcltk/pkgconfig.patch for what we do to compile Tk).
>From what I can see the only line that has actually any effect at all is Sys.setenv(C_INCLUDE_PATH="/opt/X11/include") so all the others are likely not needed, but I'm not sure of your setup so can't test.
