An error when working on reference router 1g cml

[Shandongwzl]

I am working on NetFPGA 1G CML.
My system is Centos 7. My ISE is 14.6 and Vivado is 15.2.
I have already succeeded in generating the bitfile of the project reference_nic_1g_cml.
Yet I got an error when try to generate the bitfile of reference_router_1g_cml at step 4.
I do follow the instructions of the readme:
https://github.com/NetFPGA/NetFPGA-1G-CML-live/tree/master/projects/reference_router_nf1_cml
The error message is as follows:

error.log

Could you please tell me where the problem lies?
Thank you very much.
