   What version of ATS you are using? 
   
   Anyway, we recommend to use luajit with ATS for the plugin. In 7.x luajit is part of the binary and in 8.x and beyond, the ATS lua plugin is compiled only with luajit is found in the system. 
   
   For luasocket to work with luajit, you need to compile that accordingly . This is what i do 
   
   e.g. 
   
   ```
   curl -R -O http://luajit.org/download/LuaJIT-2.1.0-beta3.tar.gz && \
   tar zxf LuaJIT-2.1.0-beta3.tar.gz && \
   cd LuaJIT-2.1.0-beta3 && \
   make && \
   sudo make install
   
   wget https://github.com/diegonehab/luasocket/archive/v3.0-rc1.tar.gz && \
   tar zvf v3.0-rc1.tar.gz && \
   cd luasocket-3.0-rc1 && \
   sed -i "s/LDFLAGS_linux=-O -shared -fpic -o/LDFLAGS_linux=-O -shared -fpic -L\/usr\/lib -lluajit-5.1 -o/" src/makefile && \
   ln -sf /usr/lib/libluajit-5.1.so.2.1.0 /usr/lib/libluajit-5.1.so && \
   make && \
   sudo make install-unix
   
   ```
