You see this error because Dan has not paid Apple to become an official registered developer and signed his releases. You have OS X configured to only allow signed apps from official developers to run.
Okay, I thought it might have been because the OSX build was actually built incorrectly as a daily. I would have hoped that not having a signature would generate a more relevant error message.
In your System Preferences, go to Security & Privacy, General tab. Click the lock, then choose Allow apps downloaded from: Anywhere.
It's working fine here on OS X 10.9.2.
If that's really the problem, then we probably need a big fat warning on the download page...
