TIMTOWTDI, sorry it's late here, forgot to rewrite pipes as backticks:
# archlib: The core .packlist
perl -MConfig -e 'print `ls -la "$Config{archlib}/.packlist"`'
perl -MConfig -e 'print `cat "$Config{archlib}/.packlist"`'
# archlib/auto: dist/bundle
perl -MConfig -e 'print `ls -la "$Config{archlib}/auto"`'
# sitearch/auto: dist/.packlist
perl -MConfig -e 'print `ls -la "$Config{sitearch}/auto"`'
# sitearch/.meta: dist/install.json and dist/MYMETA.json
perl -MConfig -e 'print `ls -la "$Config{sitearch}/.meta"`'
