Welp, that is one of the theme's that I've played around with off and on, and never quite finished converting to OTS. the theme is from back in the days before OTS and doesn't follow the same directory structure as the OTS. It assumes it is the ONLY theme you are using, and unzips that way. It would take heavy modification to make it work on a new version of litestep, or if you can find an old distro somewhere you could use that, but it's unreccommended (IMO). My suggestion would be (if your still interested in using it, that is) try updating it to OTS2, there are plenty of resourses here on ls.net to help you along, or try #litestep on irc.freenode.net, someone's always willing to help you out, or at least tell you where to find your answer.
