Package and port dependencies

Hi all,

On my server that is running 14.2, the daily security run output
has a couple of complaints:

Checking for packages with security vulnerabilities:
Database fetched: 2024-12-11T02:45+01:00
db5-5.3.28_9: Tag: expiration_date Value: 2022-06-30
db5-5.3.28_9: Tag: deprecated Value: EOLd, potential security issues, 
maybe use db18 instead
dialog4ports-0.1.6_2: Tag: deprecated Value: Consider using 
ports-mgmt/portconfig which is a dropin replacement
pcre-8.45_4: Tag: deprecated Value: EOLed by upstream, use devel/pcre2 
instead

I would love to just remove those, but I wonder if something needs them.
Is there any easy way to check if any ports or packages depend on
those packages?
