This typo is the only real error I can find in your code, except for
catching the exception the wrong way.

This should be:

  catch (luabind::error const& e)

and to get a useful error message after catching the exception, you need
to get it from the Lua stack:

  char const* msg = lua_tostring(L, -1);

If you change your code like that you will get a more descriptive error.
