For photos-to-sqlite I needed to install
osxphotos as a dependency, but only if the platform is macOS - it's not available for Linux.
Here's the magic incantation to do that:
setup( name="photos-to-sqlite", ... install_requires=[ "sqlite-utils>=2.7", "boto3>=1.12.41", "osxphotos>=0.28.13 ; sys_platform=='darwin'", ] )
; sys_platform=='darwin' in the install requires line.
