No, I only have these:

$ dpkg -l | grep lua
ii  liblua5.1-0:amd64                    5.1.5-8.1+b3                          amd64        Shared library for the Lua interpreter version 5.1
ii  liblua5.1-0-dev:amd64                5.1.5-8.1+b3                          amd64        Development files for the Lua language version 5.1
