Grove Si 1151 Doesn't complie for Teensy 3.5 Board

I just purchased a couple of the Seedio Si1151 sunlight sensors and I’m trying to add them to my weather station. I first tried the eample code provided with the libary and it will not complile using the Teensy 3.5 board. It does complie if I switch to the UNO board. MY system is all bult around the Teensy 3.5. Is there anything anyone that could help me.
Thanks in adavnce.
