[Discuss-gnuradio] Rebuilding the USRP2 Firmware in ISE 11.4

Just curious,
Has anyone actually been able to rebuild the fpga bitfile using ISE 11.4?  I loaded the files from the latest git and the .ucf, and I had 239 timing errors when the process completed.  I just thought before I started ripping through it I would ask.

Thanks,
TMB
