24.03 RC Kea not starting after upgrade from 23.09.1

I upgraded from 23.09.1 to 24.03 RC tonight and noticed that Kea was not starting after the upgrade.
I received the following crash logs (repeatedly):

[12-Apr-2024 01:29:26 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library 'intl.so' (tried: /usr/local/lib/php/20230831/intl.so (Shared object "libicuio.so.74" not found, required by "intl.so"), /usr/local/lib/php/20230831/intl.so.so (Cannot open "/usr/local/lib/php/20230831/intl.so.so")) in Unknown on line 0

Switching back to ISC for DHCP works fine, though.
Is there something that I need to do to install the missing PHP library?

Unfortunately, the PHP warnings were a red herring. The Kea server still doesn't run after fixing PHP. I don't see any messages in the /var/log files from kea.

In case others are having the same PHP issue, here's how I fixed it:
It looks like the PHP issue was a problem updating icu during the upgrade from 23.09 to 24.03.

I resolved the PHP warnings by reinstalling icu from the terminal.

pkg unlock icu
pkg delete -f icu
pkg install -yf icu

During the uninstall, it became clear that version icu-73 was still installed. Once reinstalled, I had the proper icu-74 version.
