Archivemode should look for an existing archive before attempting to build it

[dluke@…]

As I mentioned on the list, when we changed the target from 'archive' to 'unarchive' we made the time when the port isn't installed on the machine when archivemode is active much longer than it needs to be.

I think the proper behavior would be restored if we change back to 'archive' and modify archive to check for existing archives and not attempt to recreate them if they already exists.

I've got a patch that I haven't done any testing at all to yet (not even to see if the syntax is correct) that I'll attach as my first idea on how to do this.

Make 'archive' target work correctly for upgrade

[jmpp@…]

Hey Daniel! The upgrade action has been reset to archive from unarchive, so the fix for the primary issue you report will be in MacPorts 1.4. However, I'm leaving this ticket open so we can work on improving the archive target to look for already existing archives and not rebuilding them unnecessarily. Adapting ticket summary accordingly, stting myself on the CC list and the ticket itself to the 1.5 milestone.

The same is true of port install, it should look to see if the port is already installed instead of building it and failing at installation.

Fixed in r50416.
