Problem installing mods on macOS Sierra?

This may not be the cause, but...

On OS X El Capitan I was successfully able to install Dungeon Be Gone with weidu through the terminal.

Then I updated my mac to macOS Sierra. Now I'm trying to install SCS, however this time I get an error message when I try to start the installer, which is simply "Killed: 9"

This is the output.

Does anyone have any tips on how I might solve this?
