Unable to Unistall Obsolete Port py39-typed-ast Due to Dependents

[RobK88]

I am unable to uninstall the obsolete port py39-typed-ast due to existing dependents. Very strange.

bash-3.2$ port installed obsolete
The following ports are currently installed:
  py39-typed-ast @1.4.3_0 (active)

bash-3.2$ sudo port uninstall py39-typed-ast
