Linux Compiling Eden with spotyxbmc2 support

Hi to all,

i got medium knowledge in linux, but i can't manage to compile xbmc eden from akzente git.

Here's what i want.

- Ubuntu 12.04 64 bit Server as base system.
- XBMC Eden with pvr and spotyxbmc2 suppport.
- Pulse eight cec adapter sould be enabled.

I just can't figure out from what ppa to install and from what git to compile.
Maybe someone can give me a short tutorial like:

- Install xbmc from pulse-eight ppa, get specific dependencies, clone from specific git on so on.

Thanks in advance.
