Installing MakeHuman Alpha 7 Download to Ubuntu 13.04

I downloaded the Tarball for i386 linux using python 2.7 (for example Ubuntu versions greater than 10.04) to get the latest version on my Ubuntu 13.04 system (just upgraded.)
I am not a Linux power user. I extracted the files and folders from the tarball with the archive manager, and now I have a bunch of folders and files in my home/downloads/makehuman folder. I have no idea what to do next. It would have been nice if instructions for installation were included, but the only text file I found was the license.
So, how do I install MakeHuman on my system? I got the Tarball from this page
http://www.makehuman.org/content/download_alpha_7.html
On an unrealted note: is there any way to hack this grey on grey forum so that it is more readable? It is making my eyes hurt.
On another slightly related note: the earlier version of MakeHuman that Ubuntu Software Center installed shows me a black background behind the model. This is a problem on the Save page, because the save dialog is also black. black on black is invisible. It is also difficult to see any hair, since that defaults to black.
