About Automatic dependencies installation : I suggest to change
cd ~/blender-svn ./blender/build_files/build_environment/install_deps.sh
with
cd ~/blender-svn ./build_files/build_environment/install_deps.sh
Since there is no reason that a ~/blender-svn/blender should exist in the previous explainations. Alternatively, this would be possible :
cd ~/blender-svn mk dir blender cd .. ./blender/build_files/build_environment/install_deps.sh
