They aren't shown on the schematic by default. They do it this way so that people doing MASSIVE schematics don't get too overcrowded by VCC and GND pins.
You've got two options.
[1] Rename your supply and ground traces EXACTLY what they are asking for
[2] Hit the "invoke" button in the schematic editor and choose the IC. It will show the hidden pins. (On my version of Eagle it's the button above the big 'T' for text button)
