problem with bare conductive touch board program

Hi,
I've allready bought the Bare conductive Touch board, wich is a leonardo like board, for activities related with a workshop with artists in my fablab in Dax (France).
What ever I do I'm not able to make my touchboard work ! The only thing I'm able to do is to change the MP3s by popping up the sd card and changing the files in my computer.
I'm working with Mac OS 10.9.5 and I'm running the 1.0.6 version of Arduino (the last one).
The touch board is selected in the Tools---> type of board menu.
The TTY port is chosen as explained in tutorial
Whatever the .ino code I choose I have an error message. These messages always look like this : a file is not declared in the scope.

For Proximity MP3 :
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Arduino: 1.0.6 (Mac OS X), Board: "Bare Conductive Touch Board"
ProximityMP3.ino:28:29: error: Compiler_Errors.h: No such file or directory
ProximityMP3.ino: In function 'void setup()':
ProximityMP3:69: error: 'MPR121' was not declared in this scope
ProximityMP3:70: error: 'MPR121' was not declared in this scope
ProximityMP3.ino: In function 'void readTouchInputs()':
ProximityMP3:99: error: 'MPR121' was not declared in this scope

For the touch Usb midi program :
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Arduino: 1.0.6 (Mac OS X), Board: "Bare Conductive Touch Board"
Midiinterface:29: error: 'MIDIEvent' does not name a type
Midiinterface.ino: In function 'void setup()':
Midiinterface:34: error: 'MPR121' was not declared in this scope
Midiinterface:37: error: 'e' was not declared in this scope
Midiinterface.ino: In function 'void loop()':
Midiinterface:44: error: 'MPR121' was not declared in this scope
Midiinterface:49: error: 'e' was not declared in this scope
Midiinterface:67: error: 'MIDIUSB' was not declared in this scope
Midiinterface:71: error: 'MIDIUSB' was not declared in this scope

Is there any solution to avoid this with my configuration or is it only possible to make the touchboard work using Arduino 1.5.6 (with windows PC) ?

Thanks for your answers
Regards
