Indeed. 10.9.5. And ...

Yea ... lovely :-).

Oh, this is interesting. "xorg" is not installed. xorg-server is not installed.

Here's the Xorg list that I have ... somehow?

xorg-libice                    @1.0.10         x11/xorg-libice
xorg-libpthread-stubs          @0.4            x11/xorg-libpthread-stubs
xorg-libsm                     @1.2.3          x11/xorg-libsm

xorg-libxcb                    @1.15           x11/xorg-libxcb
xorg-libXdamage                @1.1.5          x11/xorg-libXdamage
xorg-libXdmcp                  @1.1.3          x11/xorg-libXdmcp

xorg-libXt                     @1.2.1          x11/xorg-libXt
xorg-libXxf86vm                @1.1.4          x11/xorg-libXxf86vm

xorg-xorgproto                 @2022.1         x11/xorg-xorgproto
xrender                        @0.9.10         x11/xrender

... How do I have some parts of the X libraries without actually having X?

Answer:
keybounceMBP:MacOS michael$ port depend xorg-libX11
gdk-pixbuf2 depends on xorg-libX11
mesa depends on xorg-libX11
xorg-libXext depends on xorg-libX11
xorg-libXfixes depends on xorg-libX11
xorg-libXrandr depends on xorg-libX11
xorg-libXt depends on xorg-libX11
xrender depends on xorg-libX11

keybounceMBP:MacOS michael$ port depend mesa
freeglut depends on mesa
libGLU depends on mesa
webp depends on mesa

keybounceMBP:MacOS michael$ port depend libGLU
freeglut depends on libGLU

keybounceMBP:MacOS michael$ port depend freeglut
webp depends on freeglut

keybounceMBP:MacOS michael$ port depend webp
ImageMagick depends on webp
gd2 depends on webp
graphviz depends on webp
qt5-qtimageformats depends on webp
qt58-qtimageformats depends on webp
keybounceMBP:MacOS michael$ 

So gd2, and others, to webp, to freeglut, to libGLU, to mesa, to the X libraries.
And gd2 is -X11.

Freeglut requires X11, it's in the library dependencies. 
Webp, however ... does not list freeglut?

Gd2 needs webp, fine. Webp is somehow grabbing freeglut, despite not listing it, and that forces a bunch of X stuff.
