Please do test the aforementioned Mac-Carbon-0.80, and report it on RT if there's a problem. Please note that you MUST build under 32-bit mode, which is especially important if you are using the standard perl that comes with Mac OS X 10.6.
I've also got new versions of Mac::AppleEvents::Simple, Mac::OSA::Simple, and Mac::Glue coming out soon. I want to get Mac-Carbon well-tested out there first, though.
