Comment (by kencu):

 If you do follow those Migration instructions, you should look at your
 {{{requested.txt}}} file of requested ports, and before you start to
 restore the ports, anywhere you see "gcc9" or "+gcc9" or similar in there,
 delete that.

 You can also delete anything that mentions gcc8 or any other version of
 gcc older than gcc11.

 MacPorts has been on a mission to get the "+gccN" out of the requested
 variants list to avoid this happening to people in the future as much as
 it was happening to people in the past.
