You are switching profiles for a board that is already setup. This
can cause trouble for Portage. If you experience problems with
build_packages you may need to run:
\tsetup_board --board ${BOARD_VARIANT} --force --profile ${PROFILE_NAME}\n
Alternatively, you can correct the dependecy graph by using
'emerge-${BOARD_VARIANT} -c' or 'emerge-${BOARD_VARIANT} -C <ebuild>'
