Terminal commands not working

[astr0nerd]

After downloading iRecovery and libusb-0.1.4.dylib and extracting them on the Desktop, I plugged my iPhone and launched iTunes. I then put my phone in DFU mode, option clicked Restore and chose the .ipsw file for 3.0.1 firmware. After the 1015 error message I quit iTunes, launched Terminal and began typing the codes precisely like how it was shown in the instructions. Unfortunately it didn't go as smoothly as I had hoped. When I got to "cd /usr/local/lib" it said No such file or directory. And when I got to "./iRecovery -s" it said No image found.

Any idea how to fix this?

I have no idea, I just followed the instructions which said to place those files on the desktop (I'm guessing for easy access)!
