This looks like it may indicate an issue with the installation of the Dropbox library in your project. How did you install the Dropbox library, and what output did you get when you did?

If something went wrong, it may help to try to uninstall and reinstall it.

I'm not sure I understand your message. Did you resolve the issue or do you still need help from Dropbox?
