It is not really permitted to install new stuff (Additions in /bin). I know i did at a point, but that was only a temporary workaround, until i got the StartupScript running.
BTW you already installed it in /usr/local/bin and that makes installing it in /bin unneccesary.
I would suggest this.
#! /bin/sh -v
# Copying program to local
cp -r ../obliterate0.4 /usr/local/
chmod -R 755 /usr/local/obliterate0.4
# Creating /usr/local/bin (if it doesn't exist)
