I remember this being the major hang up with the STALKER engine when getting it to compile for ppc64le (x-ray engine) i forgot what we did to get it to work and unfortunately i've lost all the code and work that was done due to theft of the hard drives i had been using in my system from a storage unit break in. There was some kind of working version of it though for ppc64... Also the guy who helped made it possible has vanished and most likely for the worst sad to say...
