hi In ebuild file /usr/portage/sci-libs/vtk/vtk-6.1.0-r3.ebuild it's write : video_cards_nvidia? ( || ( x11-drivers/nvidia-drivers[tools,static-libs] media-video/nvidia-settings ) ) so if you add in the file /etc/portage/package.use/package.use this line x11-drivers/nvidia-drivers static-libs it can solve the problem. ( but I don't know why static-libs is necessary).
nvidia-settings is masked for removal now, so this sort of conflict shouldn't happen again.
