--------------------------+--------------------
 It seems  that I have the same problem as described in ticket #64762:
 "port upgrade outdated" stops with an error message saying that the build
 of libgcc9 has failed. My MacOS is Monterey 12.3.1.

 If libgcc9 is not compatible with Monterey, how can I uninstall it? I have
 tried "port uninstall libgcc9" and "port uninstall gcc9". However, "port
 upgrade outdated" still stops with the same error message.
