This bash one-liner was posted to the forums; I can't find it now, so
apologies to the original author:

bash <(comm -23 <(find /usr/portage/distfiles/ -maxdepth 1 -type f -printf %f\\n | sort) <(find /usr/portage/ /usr/local/portage/ -path '*/*/files/digest-*' -print0 | xargs -0 awk '{print $3}' | sort -u) | sed -e 's|^|rm -i /usr/portage/distfiles/|')
