[pluggo] Plugin not loading in Kore 2

I saw a post that dates back to August 06, but I am having a similar problem now. I have written a pluggin in Max that does midi processing (no audio) It loads fine on a Wintel machine running XP but won't show up on my new Macbook Pro running Leopard 10.5.2; 2.2 Ghz processor, 4 gigs memory, latest version of Kore 2.02. Korwe seems to scan the plugin but it doesn't show in the Database. On the other hand, the same build shows up in the Windows version of Kore.
