If you look at your synthesis report you will find the following warnings: 

Warning: Synthesized away the following node(s):
	Warning: Synthesized away the following SERDES transmitter or receiver node(s):
		Warning (14320): Synthesized away node "FORWDGXB:inst2|alt2gxb_forwd:inst2|alt2gxb:alt2gxb_component|rx_out_wire"
		Warning (14320): Synthesized away node "FORWDGXB:inst2|alt2gxb_forwd:inst1|alt2gxb:alt2gxb_component|rx_out_wire"

Your problem is as dewiet pointed out. Your ALT2GXB instances are being synthesized away and Quartus does not allow you to declare transceiver inputs in your design without connecting them.
