After unpacking and running the executable of the current version 2.3 of Blender - a 3D animation software, I get the following errors. libSDL-1.2.so.0 not found. Subsequently, if I use LDD blender, libSDL-1.2.so.0 and libGLU.1.2.0 are indicated as not found. I checked the dir lib64 and found both of them present. I don't have an internet connection on the linux box. Any ideas/suggestion on how I can fix this problem? Thanks.
