Unable to Build/Codesign after upgrading to Snow Leopard and iPhone SDK 3.0 Snow Leopard

Question

I have no more hair to pull. Any help greatly appreciated!

Profile set to Distribution, Device 2.2.1 Distribution, as has worked in the past.

The build fails with this error: Command failed with exit code -1

The below section is highlighted in Build Results.

When you install Snow Leopard, you also need to install the Snow Leopard SDK, even if you already had the most recent SDK for Leopard.
