The linked example design (Cyclone V RGMII Example Design) contains a very subtle pointer:
Unfortunately, this INI file is missing in the design archive.
I think a 'quartus.ini' file in the project directory is meant and its contents should be
b2t_enable_hps_emac_internal_clock_arcs = on
otherwise {*|fpga_interfaces|peripheral_emac0~internal_clock } is not available and any timing constraint based on it will fail.
On a side note: I am using the latest available Quartus version (15.0 update 2).

Yup, INI file is required in this case. Just create a quartus.ini with the instances "b2t_enable_hps_emac_internal_clock_arcs = on" in your project directory will do.
You can check if the INI is being applied to your project in compilation report (after compiled), somewhere under synthesis, INI report if I remember it correctly.
