SAV MkI firmware upload compile error

When trying to upload new Marlin firmware onto our SAV MkI board, I get the following compile error in the Arduino IDE:

Arduino: 1.6.9 (Windows 10), TD: 1.29, Board: "[BootloaderCDC]SAV-MkI_RevD"

Warning: Board teensy:avr:cdcsavD doesn't define a 'build.board' preference. Auto-set to: AVR_CDCSAVD
Warning: Board teensy:avr:usbtsav doesn't define a 'build.board' preference. Auto-set to: AVR_USBTSAV
Warning: Board teensy:avr:cdcsav doesn't define a 'build.board' preference. Auto-set to: AVR_CDCSAV

Fehler beim Kompilieren für das Board [BootloaderCDC]SAV-MkI_RevD.

I have found a post on Github about this error, but I don't really understand enough about the matter to have any idea what to do.

Do I need a different bootloader for the board or has something gone wrong with my Teensy installation? I tried to compile for Teensy ++ 2.0 , but got an even larger amount of errors...

Thank you for your time!
Kind regards,
Anna

Now I tried the same with Arduino IDE 1.0.6, before I had 1.6.9.

I am now getting a new list of errors:

It still won't compile.

.... aaaand finally, down to one. I had different Arduino installations and libraries that I needed to delete, and the u8g library was missing and had to be installed. I fixed all that and have now only one error:

This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.

I don't find any information anywhere about the 'U8G_I2C_OPT_FAST' error. It has something to do with the LCD screen. Any ideas where I could look?

Kind regards,
Anna

Adding insult to injury? After removing the final error by installing a newer version of u8g:

The missing size on my board was more or less the space used by the bootloader. I still had a USBasp programmer cable somewhere, so I used that to upload the firmware (and overwrite the bootloader). Uploading the software like this is very easy, and although I was afraid to brick my board, nothing bad happened. Just plug the cable in the computer, upload a driver for USBasp (explained here), link cable to board and choose Tools > Boards > [usbtinyisp]Sav Mkl in the Arduino IDE. Choose your programmer type under Tools as well. Click upload. The process needs a few minutes to complete. There is no need to remove the jumper on the board for this.

I am very happy that I managed to sort this out - it took quite a while, but now I have a working inductive sensor installed. I haven't tried to autolevel with it yet, that will be another adventure.
