This is a portfile development question so the macports-dev mailing list would be a better place to ask. MacPorts license checking code (port_binary_distributable.tcl) does not recognize the license name "CC0" but the license is a formalization of public domain, so just write "license public-domain". You can add a comment line above that mentioning that it's really CC0, like some other ports (mypaint-brushes, libb2) already do. Some day we may overhaul our license handling to use SPDX identifiers but we don't use them as of this time.
