Merge raster fails in macOS

[aspidoscelis]

Attempting to merge rasters gives the following error message:

2020-10-06T16:07:56     INFO    gdal_merge.py -ot UInt16 -of GTiff -o /private/var/folders/s_/bbb7n2c88xl48m006s6whl700000gp/T/processing_61cdc20c4f8e4009892c992e755d9086/39a27d67b1c04437a1810e885b9d96b9/OUTPUT.tif --optfile /private/var/folders/s_/bbb7n2c88xl48m006s6whl700000gp/T/processing_61cdc20c4f8e4009892c992e755d9086/6d758ea7c6e54f4984d43fed371917a3/mergeInputFiles.txt

I first encountered this problem in the standalone 3.8 installer. I then tried the standlone 3.14, the standalone 3.10, and the kyngchaos 3.10 (which is what I am using now); all give the same 'gdal_merge.py: command not found' error. I'm running macOS 10.14.6. I tried deleting everything QGIS-related between trying the standalone 3.14 and the standalone 3.10, haven't tried it between the other installs since it didn't seem to make any difference.

I just tried deleting all the GDAL.frameworks and reinstalling 3.1 from the kyngchaos installer. That hasn't changed anything, either.

It works with the standalone nightly build becoming 3.16 release soon: https://qgis.org/downloads/macos/nightly/qgis_nightly_master_20201005_122844.dmg

It does indeed work with that build. Thanks!
