Find all the packages which are compiled with a determined env variable (or not) in a gentoo system. I needed this to get which packages still need to be recompiled with clang.
cd /var/db/pkg/
find -iname env*.bz2 -exec sh -c "bzcat {} | grep CC=\\\"clang > /dev/null || echo {} | egrep -o '(([a-z]|-)+\/\w+)' " \;
