Ok, first of all, the malloc messages are benign, so you don't have to worry about them.
Second, I don't think you can run the cvs version without the Terminal being open. I tried starting aMule with "amule --i-would-marry-my-mule &" to demonize it, but even then it is killed, when you close the Terminal window. I assume this is because it is not simply a command line executable, but instead a program within an app bundle.
So I would recommend just hiding Terminal (using command-h), so that it is out of your sight.
