Error fed by 5 non-global control signals -- only 4 control signals may be non-global

I don't believe any of our devices have on-board crystals (disclaimer: I'm a software guy, not hardware) so you have to generate the signals off-chip and feed them into the device through a pin. At that point you can use the clock directly, or use it to drive a PLL and use the PLL-generated clock. Check out http://www.altera.com/literature/lit-cyc2.jsp for more details on the hardware; to instantiate a PLL using Quartus, see http://www.altera.com/literature/ug/ug_altpll.pdf.
