It can be risky to use port reclaim for systems that can't use the buildbots as
backup, or don't have a buildbot like 10.5 Intel or 10.4 PPC.
You must be quite careful, or you'll be doing a lot of needless rebuilding.
For each port or ports that you know you want, do this:
sudo port setrequested portname(s)
Even then, it's fairly easy to make an error.
