So I am actually using the default arduino installation, and the
curious thing is that if I write a program which does something with
the leds everything compiles and runs perfectly.

But if I try to use the Serial object (for example
Serial.begin(9600);), it stops to compile.
I tried both with "ino" and gnoduino, but I don't think is a problem
of the tool..
