Library libtdbc used in restore_ports script is unsigned

[Fielding, Eric J (US 329A)]

I recently upgraded from macOS 13.x to macOS 14.3.1 Sonoma and started running the MacPorts Migration process. I got interrupted and did the minor macOS update to macOS 14.4 and tried to run the “restore_ports.tcl” script, which worked for a while but then threw an error about the libtdbc library being unsigned. I don’t know if this is something that changed recently. What is the recommended procedure for fixing this? Uninstall all the ports and reinstall them?

This is the full error:
dlopen(/opt/local/lib/tdbc1.1.7/libtdbc1.1.7.dylib, 0x0006): tried: '/opt/local/lib/tdbc1.1.7/libtdbc1.1.7.dylib' (code signature in <3CE89C0F-A387-3934-8B3D-5834290B7BD3> '/opt/local/lib/tdbc1.1.7/libtdbc1.1.7.dylib' not valid for use in process: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.), '/System/Volumes/Preboot/Cryptexes/OS/opt/local/lib/tdbc1.1.7/libtdbc1.1.7.dylib' (no such file), '/opt/local/lib/tdbc1.1.7/libtdbc1.1.7.dylib' (code signature in <3CE89C0F-A387-3934-8B3D-5834290B7BD3> '/opt/local/lib/tdbc1.1.7/libtdbc1.1.7.dylib' not valid for use in process: mapped file has no cdhash, completely unsigned?
