MacPorts 1.5 Leopard Ready?

With an impending MacPorts 1.5 release, it would be nice to know/make sure that the infrastructure code is Leopard-ready out of the box. If anybody knows of any issues with MacPorts 1.5 base code and Leopard, please let us know. Due to confidentiality issues, you may email macports-mgr@lists.macosforge.org directly. James
