I see. Could you check if your application is built for both 32-bit
and 64-bit? If it's for 32-bit only, then MacRuby will work in 32-bit
mode, which is bugged. You need to build it for 64-bit, this can be
configured in Xcode.
You can check with the file(1) command line tool if the binary
contains the 64-bit architecture.
