I that it's not possible to put GnuPG into a macOS App Bundle. GnuPG
works with absolute paths for its helper tools and daemons. Even though
the default installation location for Apps on macOS is in /Applications,
a macOS App Bundle may be installed or started from anywhere in the file
system. This collides with the absolute paths of GnuPG.
