Fortunately this is easily solved since there is a make target for dev. So add "make dev" to the ebuild and it should be good.
fixed in portage, though I have a suspicion that it should be done with devfsd conf files.
it doesnt really get created because sandbox prevents it
If devfs is running (which should be on almost ALL gentoo installations) then the device will be created automagically if there is a 1394 card to be found and the associated driver insmod/modprobe'd. doing the mknod in the ebuild is a waste UNLESS you are running a non-devfs system.
devfs will handle this
