"pins_arduino.h: no such file or directory", but it's there?

Sorry for not clarifying.

The tutorial: http://www.arduino.cc/en/Tutorial/ArduinoToBreadboard

The files included in the "Minimal Circuit(Removing the External Clock)" section. I downloaded that zip.

I then placed it in the proper file directory: the "Hardware" subdirectory.

The program being Arduino.exe, the program for programming the Arduino and uploading code.
