You certainly can't expect a binary that was compiled for an x86  
machine to run on a PS3, or any other architecture that differs from  
what it was originally compiled for.

Binary code is cpu-specific, so you would have to find a version that  
was compiled for your particular CPU, or else get the source code and  
compile it yourself for the platform you want it to run on.

Of course there is no guarantee that code which compiles and runs on  
an x86 will do so properly on a different platform. It will if it was  
properly conceived and executed, but heck, we have a lot of code  
written for an x86 that won't even compile and/or run on an amd64  
properly.
