  You need to take additional steps to complete installation.

  Your operating system security policies needs to "allow"
  running programs from $PACKAGE.

  Example: on macOS you can type open the programs in finder.

      open $HOME/bin

  Find the program(s) and right click on the program(s)
  installed to enable them to run.

  More information about security policies see INSTALL_NOTES_macOS.md
