trunk has a preliminary Objective-C API that allows pure Objective-C  
apps to initialize and use MacRuby (look at the MacRuby class defined  
in the objc.h file in trunk), and RBBundleInit could therefore be  
implemented based on that.

Could you give more details about what you are trying to do exactly?  
Loading a MacRuby bundle in a MacRuby app looks weird, you could just  
require the Ruby scripts.

If you want to load a .bundle that contains native code in a MacRuby  
app, you can use the NSBundle API. You could also generate a dynamic  
library and "require" it (assuming you have an Init_xxx exported  
function).

If you want to load a .bundle that contains MacRuby code in a non- 
MacRuby application, you will need the new Objective-C API (or use the  
standard C API) to prepare the bundle. I could work on a sample code  
that illustrates this if needed. The bundle could theoretically be  
loaded in MacRuby apps as well, thought it would be a little bit  
overkill since you could just directly "require" the Ruby scripts.
