Comment (by chrstphrchvz):

 I personally do not use this port.

 I want to say this has to do with
 plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/windeps/sunrpc/xdr_sizeof.c
 not being compiled for some reason. MySQL says it only needs to compile
 xdr_sizeof.c it with Xcode clang 10 or newer because `xdr_sizeof()` is no
 longer provided (I’ve not verified this claim): [https://github.com/mysql
 /mysql-
 server/blob/mysql-8.0.27/plugin/group_replication/libmysqlgcs/cmake/rpcgen.cmake#L45-L53].
 Meanwhile, MacPorts is instead trying to use its own clang 7 to workaround
 errors in MacPorts clang 8-9 and Xcode clang < 11: [ca0a578536/macports-
 ports].

 Note that MySQL builds fine on macOS 10.13 with MacPorts clang 7 (without
 compiling xdr_sizeof.c), and also builds fine on macOS 10.15 with Xcode
 clang 11.7 (which does compile xdr_sizeof.c).
