title: OS X Mavericks doesn't install flat packages
body: <p>I have Mavericks 10.9.4. I created a flat package using pkgbuild and productbuild and tried to install it. Everything goes fine, the UI says that the package is installed successfully, logs doesn't show any errors. Except, the package is not installed. I searched for the files, and they are not found anywhere in the system, so it's a problem with specifying location. Disabling Gatakeeper doesn't help. Using installer in command line doesn't install the package and doesn't show any problems either. </p>
  
  <p>Also, "pkgbuild --analyze " produces an empty property list. </p>
  
  <p>I downloaded MacPorts package (.pkg) from the internet and tried to install it, same thing.</p>
  
  <p>I have no problem installing bundle-stype packages. </p>
