New description:

 While trying to install xcrysden, the dependency Togl-2.0 fails during the
 compilation phase on modern macOS (Apple Silicon / arm64).

 The compiler aborts with the following error:

 {{{
 togl.c:82:12: fatal error: 'AGL/agl.h' file not found
    82 | #  include <AGL/agl.h>
 }}}

 Analysis: Apple has completely deprecated and removed the legacy Carbon
 AGL (Apple OpenGL Library) framework from recent macOS SDKs. Because
 Togl-2.0 defaults to native Cocoa/AGL detection code when it identifies a
 Darwin kernel, it attempts to include a non-existent header. The port
 needs to be patched to bypass the native AGL path and force standard
 X11/GLX paths on modern macOS configurations.

 In the future, please just attach the log, rather than converting it to a
