Can't require lua-cjson

[Hammad1029]

I have a lua script that imports lua-cjson
require("cjson")

What ever I do, running this script using gopher-lua returns:

no field package.preload['cjson'] stat ./cjson.lua: no such file or directory stat /usr/local/share/lua/5.1/cjson.lua: no such file or directory stat /usr/local/share/lua/5.1/cjson/init.lua: no such file or directory,

while running the script using the standard shell using lua script.lua runs fine
