If your Clara HD is on the same version as you are attempting to patch, you don't need to do the upgrade.

The KoboRoot.tgz file generated in the out directory is the same version as the KoboRoot.tgz file in the kobo-update-x.xx.xxxxx.zip file in the src directory and must match the version currently installed on your Kobo ereader. Basically, the relevant files are extracted from the .tgz file in the zip archive, modified, added to the generated KoboRoot.tgz output file and placed in the .out directory. This generated KoboRoot.tgz file does not contain all the files in the original KoboRoot.tgz file—if you compare the size of the two files, the original KoboRoot.tgz file is much larger than the generated KoboRoot.tgz file.

If you are really enthused, you can take the modified files from the generated KoboRoot.tgz file, inject them into the original KoboRoot.tgz and do the update and patch in one swell foop. I've done this a couple of times when playing with firmware updates but I don't recommend it for normal use unless you are fond of doing manual factory resets.
