 You can always run 'port rev-upgrade' again to fix errors.
 The following ports will be rebuilt: libgcc12 @12.1.0+enable_stdlib_flag
 }}}

 manually installing {{{libiconv}}} fixes rev-upgrade.

 I'm not sure if libgcc12/gcc12 can be made to ignore MacPorts' libiconv
 during the build. If not, or if we don't mind the dep, it looks like it
 needs a dep on libiconv.
