[MacRuby-devel] MacGem and C FFI recap for newbie?

Hi all- I poked around the MacRuby wiki and mailing list, and think I have this straight. Could someone confirm, deny or clarify: The current MacGem app works with pure Ruby Gems, but not those with compiled C components? So the FFI Gem currently won't work with MacGem? If I want to use a C dylib like libsndfile with MacRuby, the easiest way to go is to create an Objective-C Framework to wrap around the dylib? Thanks! Charles
