First of all shouldn't the name of the script have been pkgscan...?

When i downloaded the script by using the download function on pastebin the file had WinBlows newlines (^M) in it, so first I tried a search and replace in vi but that didn't work (%s/^M//g), so I ended up copy/pasting from the site instead.

I've attached the script. unpack with tar -xf pkgscan.sh.tar... The script is called pkgscan.sh because it's a shell script.
