chmod: Operation not permitted (Need terminal help)

[Zal91]

Before you type the commands type

su root

It will ask for your password. (It's alpine unless you changed it)

Then you can type those commands.

So I'm installing an app that's not on Cydia and I don't have a wi-fi router so I'm using DiskAid. The App guide asks me to run the following commands in Terminal:

chmod -R 0755 /Applications/Transformer.app
chmod +s /Applications/Transformer.app/Transformer

Each of these commands give me a "Operation not permitted error" and I'd like to know how to fix this.

Screenies:

First Screenie: Terminal startup...seems a little strange to me it didn't use to do this

2nd: First command (-R 0755)

3rd: Second command (+s)

I'm not sure what I'm doing at all to tell the truth. I have no experience with Terminal that doesn't involve ".gettorrent/"...please help =[
