Hey gang - I've uploaded Yet Another Test Build, to:
It has all three support bundles (Panther, Tiger, Leopard), and is compiled with @executable_path, so you should be able to simply drop it into your .app bundle to run your apps on Leopard. Aside from PAR bundles, that is - this is just the bare framework. PAR bundles are compiling as I write this.
Looking forward to your feedback!
