As a quick fix, have you tried using dlopen() instead? It is recommended
on OS X (by Apple, see http://lua-users.org/wiki/BuildingLua).
Still, I'm a little surprised that the bundle was loaded twice.
Could this be a bug? Isn't package supposed to load the bundle/so/dll
only the first time the module is required, and the other times to use
the previously opened shared library handle, find the luaopen_XX symbol
using that handle, and call it again in the new state?
The package module definitely keeps the load handle around, I don't see
why it shouldn't use it!
