#70269: GDAL Missing PDF Support (at least when installed as dependency for QGIS3)

----------------------+--------------------
 **The issue**
 The GDAL build via MacPorts as part of qgis3 installation currently lacks
 support for PDF files, which means qgis3 behaves as though PDF files don't
 exist.

 **Expected behavior**
 GDAL should be built with poppler to enable PDF support.  I was able to
 fix the problem with `sudo port install poppler` followed by `sudo port
 install gdal +pdf +poppler`

 **Steps to reproduce**
 1. Install GDAL as a qgis3 dependency via MacPorts using `sudo port
 install qgis3`.
 2. Attempt to open or georeceference a PDF in Qgis3
 3. Run `gdalinfo --formats | grep -i pdf`.
 4. Observe that PDF support is not listed.

 **System Information**
 - OS: macOS: Sonoma on M3 Max
 - GDAL Versions:
   Broken: `gdal @3.9.0_0+postgresql16+proj9`
   Fixed: `gdal @3.9.0_0+poppler+postgresql16+proj9`
