Tried to get Blender working. Installed 2.45 from the fbsd ports. Compiles and installs fine. Everything is fully up to date.
However if you start blender it'll crash X, nothing in Xorg.0.log except a signal 11 message.
Downloaded the pre-compiled version 2.47 of the blender site, same deal. Start blender and X crashes.
Installed the nvidia 177.70 beta driver and blender works
