Similar thing happended to me, I simply forgot to set dep=TRUE, and afterwards, was annoyed, when I had to reinstall the packages that were already installed.
Therefore the changes I made wouldn't prevent a rerun with dependencies=TRUE, because the packages which are already installed are not excluded from "pkgs" until the dependencies have been checked.
