Ah, so "c" will not give it into being clobbered.

And Josh, the parent dir doesn't allow nuking the file:
dr-xr-xr-x   3 root  wheel      5158 Oct  4 19:17 dev



Do we have a stray case where MacPorts not dropping privileges?
Does /dev/null still get deleted when run as a normal user instead of root/macports?
