I've tested the upgrade many times over and I don't expect any problems, but if you run into any, please let me know.

it fails when using 'direct' mode (instead of image mode):

Simple workaround is to uninstall p5-libwww-perl (with force if necessary) and then install it again.

(the problem is the pre-activate method in p5-http-date assumes image mode).

I've thought this over a bit.

In direct mode, there is only one version of each port installed. So to have the same upgrade behavior in direct mode, p5-libwww-perl would simply have to be uninstalled.

But if a failure occurs, then the system is left with no p5-libwww-perl. That makes me uneasy. (At least in image mode, a deactivated p5-libwww-perl is still installed.)

So I think the "workaround" given above may actually be the best route for direct-mode users to go. Thus I would want to edit this port, p5-libwww-perl, and all of its dependents so they would inform direct-mode users of this necessity, rather than simply allow upgrades to fail without explanation.

Objections? Other suggestions?

I think it's OK to uninstall/install for any direct mode users. Upgrade for direct (+archive mode) works by building the new archive, uninstalling, and then installing the new port.

Since it's happening in pre-activate (which is after destroot), you already should have a successful build.

Direct mode is no more.
