If require fails, it should throw an error, which message lists the
various paths that were tried to locate the module ('random'). Can you
send us the complete error message with the path list and the stack
trace ?

Note that your C code only checks for compilation errors, not runtime
errors. You should check the return value of luaL_dofile. Also since
luaL_dofile is loading the file itself (and will report compilation
errors too), the call to luaL_loadfile is just useless in that case.
