Error compiling for board [BootloaderCDC]SAV-MkI.
I'm not familiar enough with TeensyDuino to tell you exactly what you need to do. I see in the wiki they say:
The instructions here will help you setup the development environment using Arduino´s IDE version 1.0.6. Currently working in getting it going on Arduino 1.6.5.
This tells me that the boards.txt file is in the old format. The easy way would be to just use the Arduino IDE version the thing was written for but that's not to say it's impossible to get it working in Arduino IDE 1.6.8(actually I recommend 1.6.9 since 1.6.8 had a fairly serious bug). There is a guide on how to convert from 1.0.x format to 1.6.x format here:
The problem is that it looks like teensyduino has a slightly different format. I might be able to infer what changes are necessary if you post the original teensyduino boards.txt file.

Those are nothing to worry about. They are annoying but are only warnings and can easily be fixed.

That's the real problem and I don't see anything in the modified boards.txt that would cause it. I think reinstalling the Arduino IDE and Teensyduino is the best solution in case . Make sure to install v1.29 that supports Arduino IDE 1.6.8.

Error compiling for board [BootloaderCDC]SAV-MkI.
After the upload fails you will see a button on the right side of the orange bar "Copy error message". Click that button.
Paste the error messages here using code tags(</> button on the toolbar). If the forum doesn't allow it because it's too long then attach it as a text file. This is better than pastebin because it's easier for other forum users to take a look. We can use all the help we can get, right?

i just click verify/compile as i dont have the printer close enough that i can upload
That's fine. From your previous error message I couldn't tell if the problem was occurring during compilation of upload. Now I can see it's during compilation so it would never get to the upload anyway.
Try the attached boards.txt file, following my previous instructions. I only added the new modifications to the [BootloaderCDC]SAV-MkI board since that's the one your error message indicates you're using.
Well I did try but unfortunately I'm stumped. I'm not familiar with Teensyduino at all, don't have any of those boards and only installed once to help someone with an easy issue. The problem is the tool name is not being defined. It should be filled in at the end of the path: "C:\Users\Bo\Desktop\Arduino IDE\arduino-1.6.8\hardware\teensy/../tools/" in the commands. Now that you've provided a decent amount of information hopefully it will help someone more knowledgeable to help out. If you wait a while and no help appears here you could try the reprap or teensyduino forums. Cross posting is not usually a good idea so please only post to one at a time and provide the link this thread as well as the error message and the link to the installation instructions so that nobody will duplicate effort trying to provide an answer when it was already done on the other thread.
