You said before that you are using an arduino pro mini board, right ? This board has already an xtal !
You only need to add an xtal if you're making your own board with a atmega328p chip on it.
Your compile errors are because you're using the Arduino libraries (through the IDE). You should compile directly with "make", Sean has a bit modified the underlying serial libraries...
