The following USE changes are necessary to proceed:

NOTE: This --autounmask behavior can be disabled by setting
      EMERGE_DEFAULT_OPTS="--autounmask=n" in make.conf.

Use --autounmask-write to write changes to config files (honoring CONFIG_PROTECT).

подскажите пожалуйста куда копать?

запусти

emerge postfixadmin --autounmask-write

может ругнуться на отсутствие файла

надо будет создать файл по пути в ошибке
примерно:

touch /etc/portage/package.use/postfixadmin

а дальше по инструкции
