The timing was so bad that it didn't get beyond the mapping stage. Follow the instructions in the error message: "Please use the Timing Analyzer (GUI) or TRCE (command line) with the Mapped NCD"
so run the $XILINX/settings64.sh and then timingan and use the "open design" option to open the system_map.ncd (or something like that, I'm going from memory) in the implementation directory.
