I wanted to follow up on my somewhat cavalier comment a couple of days ago about doing emerge -C on a dependency. It was a bad comment for me to make without adding some discussion around it. This can actually harm your system if you emerge -C the wrong dependency. For instance, emerge -C gcc or python is likely a bad thing to do as you will be unable to build anything to get the system fixed again. However emerge -C jack-audio-connection-kit as a dependency for something like Ardour wouldn't harm the system but would demonstrate what I was talking about. Any new user reading this thread at some future date should ensure that (at a minimum) if they emerge -C anything at all that at least it's not part of @system. emerge should warn of this but it's best to do a little study before pushing the enter key. Cheers, Mark
