The default profile is what you need.
Please don't do USE="-*". It breaks things.
* Long ago, setting a useflag always meant "adding things to the default". For
some years now, we have use-defaults, which means an ebuild can set whether a
use flag set not by profile and not by user is on or off. If you add "-*" to
your use flags, you turn all default-on useflags off too (which means you may
switch away from upstream defaults a lot).
An example where this may lead to trouble: you end up with sys-devel/gcc[-
cxx], i.e. a compiler that cannot translate C++.
* The dependencies on specific Python or Ruby versions are controlled via
useflags. Basically, if Python package X needs Python package Y, both have to
be installed for the same Python variant for things to work. If you disable
all useflags via "-*", you basically disable support for all variants. Bang.
* Similar for multilib installations.
