LUAROCKS config gives errors

I installed luarocks-2.2.1-win32 from here:

http://ift.tt/19lbaYL

and the installation was simple. There is a .bat file that does it all. But unfortunately, the rocks that are downloaded are not recognized by LUA. I checked my LUA install by issuing

luarocks config 

and get this:

Anyone have experience with installing LUArocks into windows?
