Whilst I was figuring out how to create packages on Launchpad and as I was looking for something that would also benefit others, I created packages for Wily Werewolf (15.10).
Please feel free to test them. I will keep these until Maarten Baert officially releases the Wily versions. I will then delete these from my PPA.
