[Part 3] Download torrent & newsserver packages

[freem@n]

hi guys.
I would like to use the latest beta version of NZBGet because there are a lot of cool changes. Is it possible to just install it like I would in Raspbian for example (download source, build, install)? this would be no problem... or do I have to make some XBian-specific changes?
The same goes for SickBeard. I would like to use a german fork of SickBeard which runs great in Raspbian but I have no idea if I can just do the same installation process (git clone) in XBian.
