Comment:

 Replying to [ticket:26585 tommyd@…]:
 > I haven't upgraded my ports installation for quite some time, so
 recently triggered `port upgrade installed` unattended and thought it
 should be finished after a couple of hours. But unfortunately it got stuck
 in between, while it tried to upgrade several old (apparently removed in
 upstream MP) ports like `p5-io-compress-zlib`.

 no longer existant and would rather mark the particular ports for removal
 instead of trying and failing to install them.

 MacPorts base already has this capability since version 1.8.0; it's called
 the `replaced_by` keyword. But it's up to individual port maintainers to
 remember that this capability exists and to employ it when renaming ports.
 In this case (see #21167), the p5-io-compress-zlib port should have been
 retained and marked as replaced_by p5-... (whatever it was replaced by),
 instead of being deleted immediately.

 However, we do remove the replaced ports after awhile, when we remember to
 do so. I typically recommend this be a period of no less than one year; I
 would hope users would update their ports at least once a year, hopefully
 much more frequently. Unfortunately in your case it looks like your ports
 are over a year old, so even if we had used the replaced_by feature, it
 probably wouldn't have helped you now. See #21167 for recommendations on
 how to complete this particular upgrade, if you still need assistance.
