 I'm seeing the following errors on a MacBook Pro 15" Core i7 after
 downloading the 1.9 binary. Just to be clear: I haven't compiled from
 source, just trying to use the latest binary distribution on a core i7

 $ sudo macgem install rack

 Interestingly, the macruby interpreter runs without error.

 "macgem --help" and "macgem --version" also run fine (but these options
 produce errors with macirb or macrake).
