Do not use the list command, it does not give you the version number you
expected. The problem here is, list reports version 0.86 which the
latest available version of p5-test-simple, and that's what list is
supposed to do. But this does not mean you have p5-test-simple @0.86
installed.

Instead, use:
  port installed inactive

It will give you more accurate information and tell you the real
versions you have installed.
