gnump3d-2.9.6 is out and fixes some security bugs among other improvements (I don't know if they are in the latest Gentoo version of 2.9.4 or if they were introduced later). In any case, upgrading would be great, copying over the ebuild worked fine for me, nothing seems to have changed (installation-wise). TIA
