as it seems at the moment (16.08.13), the blender build in the repos (weekly) is "flawed" enough (missing the entire cycles rendering engine due to a missing useflag -cycles, and "obsolete", current version minus two) for me to look into the alternatives..
so far i have turned to the portage way, only for blender..
these i will try to install first "manually" (entropy): http://packages.sabayon.org/show/blende ... -show-what
to minimize the dependency issues later on..
this is my first sabayon and any gentoo based system, so, experienced with these package managers i am not..
this is the idea, still searching for a proper syntax, but basically:
install nvidia drivers,
install the blender dependencies,
install blender (portage),
"tell" entropy to disregard blender,
update system (entropy, obviously)..
any suggestions are very very welcome..
will post here in detail on how it went/ goes..
