Using zsh as my default shell, on 0.9.4 the install.sh fails with a:
-e -n Should we CONTINUE?
install.sh: 44: read: Illegal option -n
install.sh: 45: install.sh: [[: not found
install.sh: 247: install.sh: Bad substitution
root@harv1:~/plot_manager# bash install.sh nas
Simply re-running it using bash install.sh nas fixes it.
