If an entry in the dep file is not in the repo, and also is not present in the current directory with the batch being checked with submitqc4, then it is listed as a wrong dep file entry. If it is present in the current directory, it will be mentioned in green text.
I don't see netfilter-3.0.21-tinycore.tcz listed as missing when I check conntrack-tools, as I run a 3.0.21 kernel now, and I don't know why it would not also work with 3.0.3, and I don't have a 3.0.3 to test with.
