git clone git://github.com/Grive/grive.git
The file /root/grive/bgrive/doc/grive.1 was missing in my case, so I've created a dummy file in order to finish the installation. I didn't figure out however why it was missing. As it's only the man page for grive, I considered it less important.
The first time, you need to authorize grive to access your Google Drive, there fore do:
And follow the instructions (you will have to log into your account with a browser, confirm that you want to allow grive to access your drive and copy paste the given code to the terminal, pretty easy).
Then start the synchronisation for example like this: /usr/local/bin/grive -p /home/<user>/<google-drive-folder>
