VL7 comes with Scribus 1.3.8. I, too, hope that the final release of VL7 will include whatever is the latest version of Scribus, hopefully 1.4 by then (it's supposed to be out soon).
Meanwhile, I compiled Scribus 1.3.9 with no problems whatsoever on my VL7 alpha system. So if you really can't wait, download the source and compile it yourself. cmake-make-make install. Directions are included with the download of the source code.
