require('image') not working in Torch7

I have installed 'image' package using luarocks

$ luarocks  install image

and everything gets installed without any error. Whenever I try to use it the following error is returned:

Can anybody please help me in this? I am a newbie in Torch7 & LUA.

PS: I am running Ubuntu 14.04 and have installed Torch7 according to the official instructions and everything else is working fine.

Hit the same problem. Doing

luarocks install sys

as well worked for me. Not sure what happened to sys with the image install.
