libunwind-headers used to require CarbonHeaders. It no longer does, and CarbonHeaders are now obsolete and should be uninstalled. You can either uninstall libunwind-headers, and they will be reinstalled later if needed, or you can upgrade libunwind-headers to the version that doesn't need CarbonHeaders. Then you can uninstall CarbonHeaders.
