[R-SIG-Mac] Compiling Cairo package

[Simon Urbanek]

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.

Cheers,
Simon
