From http://www.lua.org/manual/5.1/manual.html#pdf-require:

When loading a C library, require first uses a dynamic link facility to link the 
application with the library. Then it tries to find a C function inside this 
library to be used as the loader. The name of this C function is the string 
"luaopen_" concatenated with a copy of the module name where each dot is 
replaced by an underscore. Moreover, if the module name has a hyphen, its prefix 
up to (and including) the first hyphen is removed. For instance, if the module 
name is a.v1-b.c, the function name will be luaopen_b_c.

So my first guess is that you'll need to rename or alias Hello_Init to 
luaopen_hello.
