Thanks -- but ego and epro aren't available( app-admin/ego wasn't in stage3), and I can't emerge any packages with an invalid profile:
# emerge ego -va
!!! Unable to parse profile: '/etc/portage/make.profile'
!!! ParseError: Parent '/usr/portage/profiles/funtoo/1.0/linux-gnu/arch/arm-32bit/armv7a_hardfp' not found: '/etc/portage/make.profile/parent'
!!! Your current profile is invalid. If you have just changed your profile
!!! configuration, you should revert back to the previous configuration.
!!! Allowed actions are limited to --help, --info, --search, --sync, and
!!! --version.
