Update:

I've found a post on a Hackintosh site that describes the issue exactly:

https://www.tonymacx86.com/threads/solved-taskgated-service-exited-with-abnormal-code-2.263859/

Every 10 seconds I was getting these error messages in 
"/var/log/system.log":

May 29 02:49:05 whdmac com.apple.xpc.launchd[1] 
(com.apple.taskgated[394]): Service exited with abnormal code: 2
May 29 02:49:05 whdmac com.apple.xpc.launchd[1] (com.apple.taskgated): 
Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

I took the poster's advice and unloaded the 2 "taskgated" LaunchDaemons 
and now my MacPorts binaries are working again.  I have no idea why 
Security Update 2020-003 broke this particular Mac's "taskgated" but 
like the poster it looks like I'll probably have to re-install Mojave to 
try and fix it.

Thanks to Franco Vaccari and Prokash Sinha for their kind responses.
