Loading native code lua modules

Question

I'm trying to load a C lua module into my Lightroom Plugin. Unfortunately I can't get it to work and keep getting the error:
An internal error occurred
Could not load toolkit script: PluginGUI-OSX
This is an Objective-C code lua library and the error occurs on the following line in my lua script:
require 'PluginGUI-OSX'
I've also tried preceding this with the following, but still I get no luck:
package.path = package.path..";./?/init.lua;./?.so"
Has anyone ever had luck trying this? Or does anyone on the Lightroom team know it to be impossible?
Thanks in advance
Rich

Hello,
I've got a similar problem. But I don't want to include native code. As in every example plugin I've found, I wanted to extract portions of my code to other scripts (just as FtpUploadTask.lua in FTP example)
But whenever I add the following line to my ExportServiceProvider I get an error:
require 'RhubarbHttpClient'
The error message looks as described in the post above:
Plug-in error log for plug-in at: /Users/krizleebear/Library/Application Support/Adobe/Lightroom/Modules/rhubarb-gallery.lrdevplugin
**** Error 1
An error occurred while attempting to run one of the plug-in’s scripts.
Could not load toolkit script: RhubarbHttpClient
**** Error 2
Could not load the post-processing filter from this plug-in.
Could not load toolkit script: RhubarbHttpClient
When I just put my code from RhubarbHttpClient.lua directly into my ExportServiceProvider, it's working.
The full code can be viewed on google-code:
