What have you done to the sketch? It now just gives a ton of build errors for the latest -git version.

/root/arduino-1.6/sketchbook/BlueGigaEmpeg/BlueGigaEmpeg.ino: In function 'void setup()':
BlueGigaEmpeg:741: error: invalid conversion from 'const __FlashStringHelper*' to '__FlashStringHelper*' [-fpermissive]
Log(F("Built in Arduino Serial has been started."));
^
BlueGigaEmpeg:1860: error: initializing argument 1 of 'void Log(__FlashStringHelper*)' [-fpermissive]
void Log(__FlashStringHelper* logMessage)
^
BlueGigaEmpeg:748: error: invalid conversion from 'const __FlashStringHelper*' to '__FlashStringHelper*' [-fpermissive]
Log(F("BlueGiga Serial has been started."));
^
...

I'll look at the commit history I guess.
