Recovery from p5-io-compress-zlib conflicts with p5-io-compress? was Re: How to install Perl modules

[David Corking]

I selfupdate'd macports and then tried a
sudo port upgrade outdated

This produced a conflict between the above packages which I attempted
to resolve with three forced uninstalls.  I attempted to follow the
suggestions at http://trac.macports.org/ticket/21167 ,  a similar
conflict, but I think I have been a bit heavy-handed.  On trying to
re-install the perl libraries, I get

g$ sudo port install p5-io-compress
--->  Computing dependencies for p5-io-compress
Error: Target org.macports.activate returned: Registry error:
p5-io-compress 2.021_3 not registered as installed.
Error: Status 1 encountered during processing.

Any suggestions as to how I could fix the registry and proceed with
the upgrades?

Below, I pasted a lengthy edited transcript of the circular
dependencies that occurred in the middle of the upgrade, and my
attempts to resolve them, in case it sheds extra light.

Best, David
