3rd party boards

I have installed de board Momote on the IDEARDUINO but when I will go compiling this board I receive the following mistake. Somebody can help me ?

Looks like a code error. Post yours so we can advise on a fix.
Please use the code tag button, </>, on the menu.

I did not write any code I just compiled the file in the IDE with the momote card selected
