If you download the SDK beta (and I think also RC) the structure is changed :-)
You have the headers without links, no sources inside. You can also download / install the sourc4s with the installer, but it is different from the pure source package where the include files from include point to the sources dir.
To rebuild Qt, you now have to download the real source zip or tar file.
