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.
