Confirmed. I found this in image.c:
/* XPM support functions for NS where libxpm is not available.
Only XPM version 3 (without any extensions) is supported. */
I suppose to get xpm2 support you’ll have to find a version of libxpm
somewhere.
There is an error logged in *Messages*, perhaps it should specify XPM3
per the attached patch.

Yes. In addition, I'd add an entry about this in PROBLEMS.
Thanks.

Done. I created a subsection for macOS, although I’m not sure if this
is actually a macOS specific issue, or general to systems lacking X11
libraries (MS Windows?).

The MS Windows build of Emacs uses a hacked version of the X11 libxpm
library, so this problem doesn't exist there.

^^^^^^
A typo.
