I've reconfigured with these settings [1]:

* luarocks tree: /usr

[maybe architecture-specific components]
* rocks: /usr/lib/lua/luarocks/rocks-${LUA_VERSION}
* manifest: /usr/lib/lua/luarocks/rocks-${LUA_VERSION}/manifest
* deploy_bin_dir: /usr/lib/lua/luarocks/bin
* deploy_lib_dir: /usr/lib/lua/luarocks/${LUA_VERSION}

[architecture-independent components]
* deploy_lua_dir: /usr/share/lua/luarocks/${LUA_VERSION}
