I've assembled the project at
Reddit - Dive into anything and have run into a snag getting it to compile. Incidentally, it does compile for different boards such as the uno.
the code is as follows...

#define BUTTON A5
Encoder encoder(APIN,BPIN);

I downloaded the arduino board definition from
and loaded it into my arduino IDE. I also downloaded the libraries for the ws2812b, the RTC, and the encoder. I used the encoder library from
https://www.pjrc.com/teensy/td_libs_Encoder.html
but when I go to compile it (with board set to Mighty 1284p using optiboot) i get the following errors...
This report would have more information with "Show verbose output during compilation" enabled in File > Preferences.

In file included from clock.ino:2:

I think it has to do with the interrupt_pins file in the encoder library. Any help would be greatly appreciated.
