You will also need:

    sudo apt-get install liblua5.2-dev

and you don't need to purge lua5.1 to install/use lua5.2 ...

... and luarocks pulls lua5.1 back in anyway!

The LuaRocks version in the Ubuntu/Debian repositories is too old and 
only supports lua5.1. Try installing a more recent version manually. I 
use something like

    wget http://luarocks.org/releases/luarocks-2.1.1.tar.gz
    tar xzf luarocks-2.1.1.tar.gz
    cd luarocks-2.1.1
    ./configure --prefix=/home/siffiejoe/programs/luarocks 
--lua-version=5.2 --lua-suffix=5.2 
--with-lua-include=/usr/include/lua5.2 --versioned-rocks-dir --force-config
    make bootstrap

to create a local LuaRocks installation in my home directory.
