I've cobbled together a script of my own to handle this. It's
/root/bin/autodepclean : NOTE: it does *NOT* clean out anything.
Rather, it generates a script "cleanscript" in the current directory.
The idea is that you inspect it first before running ./cleanscript

#!/bin/bash
# autodepclean script v 0.04 released under GPL v3 by Walter Dnes
# 2023/02/18 Generates a file "cleanscript" in the current directory to
# remove unused ebuilds, including buildtime-only dependancies.
#
# Warning; this script is beta. I recommend that you check the output
# in cleanscript before running it.
#
# With the arrival of "virtual/editor", the script now suggests removing
# app-editors/nano, which may not be what you want. If you want to keep
# nano, put it into world.
#
# version 0.03 disables the removal of gentoo-sources. Your current kernel
# is not always the most recent one in /usr/src.
#
# version 0.04 adds "--verbose" to the "emerge --depclean". This makes it
# easier to track down circular dependancies.
#
# version 0.05 wipes cleanscript if no files to process. This guards
# against the edge case of running a flat "emerge --depclean" if there
# are no ebuilds to remove.
echo "#!/bin/bash" > cleanscript
echo "#" >> cleanscript
echo "emerge --depclean \\" >> cleanscript
emerge --pretend --depclean |\
grep -A1 "^ .*/" |\
grep -v "^ \*" |\
grep -v "^--" |\
sed ":/: {

}" | grep -v "=app-editors/nano" |\
grep -v "=sys-kernel/gentoo-sources" |\
grep -v "=sys-devel/gcc-" >> cleanscript
echo ' ; echo ""' >> cleanscript
echo "revdep-rebuild" >> cleanscript
chmod 744 cleanscript
if grep "=" cleanscript >> /dev/null 2>&1 ;
then
echo "OK to proceed."
else
echo "" > cleanscript
echo "Nothing to process"

I last updated my system 32 days ago. When I ran "autodepclean" after
updating world today, it generated the following "cleanscript"

autodepclean takes out a lot of "virtual-perl" packages after a perl
update, but doesn't cause problems.
