/usr/share/games/toribash/toribash.bin: error while loading shared libraries: liblua5.1.so.0: cannot open shared object file: No such file or directory
Began by trying to make a symbolic link to your file in liblua.so.5.1 naming liblua5.1.so.0
ln -s liblua.so.5.1 liblua5.1.so.0 ln-s liblua.so.5.1 liblua5.1.so.0
It is indeed possible that the software research this file, but under a different name. However, attention to a possible change of the file during an update, the link will not follow automatically.
ln -s liblua.so.5.1 liblua5.1.so.0
ln -f -s liblua5_1 liblua5.1.so.0
