Xilinx programming on OSX (Found an SP601)

An engineering company I interned with were shutting up their design centre, and the guys invited me in to pillage the corpse. I lucked out and found a Xilinx SP601 FPGA. I've finally got some time and inclination to start playing with it, but unfortunately I lucked out again and got a macbook as part of a studentship. I can't find any FPGA tools for osx.

I have a linux box so can us that in a pinch (I think ISE WebPack will work?), but I'd love to be able to use my macbook. Anyone know of fpga toolchains?
