gdal @3.7.2: not built with GIF support?

[PaulWessel (Paul Wessel)]

On Windows, GDAL 3.7.2 gives this

gdalinfo --formats | grep GIF
  GIF -raster- (rwv): Graphics Interchange Format (.gif)
  BIGGIF -raster- (rov): Graphics Interchange Format (.gif)

but on macOS version 3.7.2 the gif format is not listed. I install gdal via

sudo port install gdal +hdf5 +netcdf +openjpeg

and this is the first time I notice lack of GIF support. Is this an omission, policy change, or a new variant I must add (e.g., +gif)?

I notice my gdalinfo says this

gdalinfo --version
GDAL 3.7.2, released 2023/09/05 (debug build)

MacOS Ventura (13.5.2)

The gdal port declares a dependency on the giflib port and it uses the configure argument -DGDAL_USE_GIF=ON so I think the intention was that gdal should have gif support. But at configure time it has this somewhat conflicting output:

-- Found GIF: /opt/local/lib/libgif.dylib (found version "4.2.3") 

-- The following OPTIONAL packages have been found:

 * GIF
   GIF compression library (external)

-- The following features have been disabled:

 * gdal_GIF, Graphics Interchange Format
