XCODE 4 fails to install in LION

I did a fresh install of Lion using the rescue usb disk and it seemed to be going well until I downloaded XCODE 4 from the App Store. The program fails stating I need to contact the Developer.

I'd appreciate some help understanding what I need to do to get XCODE working.

Here's the output from /var/log/install.log
