Make the message window larger and you will see the light...

Unfortunately I have already tried expanding the message window. The errors which I posted are the only error output which I get even when I turn on verbose compilation.
If you are trying to reproduce my issue you will need to add all of the same libraries to your arduino workspace libraries folder:
https://github.com/mchr3k/arduino/tree/master/libraries. This includes the latest SdFat library which I think fixes the error you are getting.
Unfortunately I can't do better than linking to GitHub as I am posting from my phone. I will try to put together a more helpful zip of the required files later today.
