Xcode 4.3 was just released and several aspects of MacPorts 2.0.3 and the ports we currently have are probably incompatible with it. I recommend you use Xcode 4.2.x until we can sort this out.

However, it's unclear from your report what component you're having a problem with: a port (what port?) or MacPorts base (what part?).
