First port installation fails

I did that, and it said:

macpro$ sudo port -f install p5-pathtools
--->  Installing p5-pathtools 3.25_0
Error: Target org.macports.install returned: Registry error: p5-pathtools @3.25_0 already registered as installed.  Please uninstall it first.
Error: Status 1 encountered during processing.

So I now try "sudo port install firefox-x11" again.  It aborts with

I try to install firefox-x11 yet again, and yet again it fails in the
same way, this time for p5-test-harness.  Then p5-test-simple.
After that it seems to proceed happily.  But surely we're not
supposed to have to do this by hand?
