I can try to compile here installing teensyduino and selecting the board, even without the boards.
trying to compile any example I got this errors

Thank you!

Hi,
I add a fix,
but I use TEENSYDUINO key and I test It in Teensyduino
Please test this fix if It's correct.

@xreef thanks for the quick fix. I can compile and upload to Teensy.
For some reason (probably my fault) I can't make it work with a simple setup I'm testing here (push button handling, with or without interrupt).
I have a protoboard and everything is working with Wire.h
Let me know if you want some additional testing

[xreef]

Please, send me your working code with wire.
Thanks
