[Q] how to uninstall "not registered" inactive ports

[Kuniaki Mukai]

Hello

I have two inactive ports, which I want to uninstall. 
But I got only "not registered" message.

I appreciate if some one give me any hint on  how to uninstall 
such inactive ports. 

% port list inactive
p5-test-harness                @3.14           perl/p5-test-harness
p5-test-simple                 @0.86           perl/p5-test-simple
% port list inactive
p5-test-harness                @3.14           perl/p5-test-harness
p5-test-simple                 @0.86           perl/p5-test-simple
% sudo port uninstall  inactive and p5-test-*
--->  Unable to uninstall p5-test-harness 3.14_0, the following ports depend on it:
--->  	p5-test-simple
Error: port uninstall failed: Please uninstall the ports that depend on p5-test-harness first.
% sudo port uninstall  p5-test-simple at 0.86
