Have I seen it [i]not[/i] successful remove itself? I see a couple of hints in Google searches having to do with the security/auth framework complaining. There are also threads with less-than-graceful ways of dealing with that occurrence on macfixit, but it shouldn’t be directly related to your build, since we’re usually doing things in the cleanest way possible. What system did you build on? If you could post or link a pastie of your log(debug is probably unnecessary)? That would be a good starting point to see if it is build related(the repair permissions it does at the end should be all you need to clear install issues, assuming you’re building on a fully patched system). Are there possibly any proxy/firewall rule considerations on the network you’re testing on?
