 Capabilites are the write access to the target you want to modify in
your eselect module:

test_for_root() {
	# checks if the user has rights to modify /usr/bin/
	[[ -w "${ROOT}/usr/bin" ]] || die -q "You need to be root!"
}

 That's how the the vim and Emacs eselect modules do it.  In my opinion
the best way to check for the rights needed.
