It's possible there's a dependency cycle in one of your ports (i.e. A depends on B depends on C depends on A). We don't allow dependency cycles, but every once in awhile they are introduced accidentally. MacPorts itself doesn't handle dependency cycles well, and it's possible restore_ports.tcl doesn't either. At this point I couldn't tell you which of your ports might be affected by that. If you can narrow it down, let us know. (Try restoring half your ports. If that works, try restoring the other half too.)
