The cache is keyed by OS version and list of packages to be installed, with no other forced invalidation right now. So it's hard to predict when a new version of a package will be picked up and it will differ between git repositories.  I've been wondering whether the cached macports install should just be regularly generated instead, along the other ci images.

The change is not in a release yet.  We could have macos install IPC::Run from
github, or I could get a release cut so it can make its way to macports.
https://ports.macports.org/port/p5.34-ipc-run/builds/ suggests it ingested the
last release within a couple days of release, so macports itself may add
negligible latency.
