I am able to build a 4-way universal of glew on Mac OS X 10.5.6 with  
Xcode 3.1.2 and MacPorts 1.7.1.

Note that libGLEW.a is a static library. I'm not aware of how to  
determine what architectures a static library is built for. Usually  
you would be using a dynamic library, like libGLEW.dylib, for which  
the "file" command should verify its architectures.
