 check whether the default system libraries are 32-bit or 64-?> bit; the
 processor type is always reported as x86_64 by gcc on recent Macs, so this
 is not a reliable indicator. I will look into a > reliable way to detect

 You probably want to look for a Darwin Kernel Version >=10 and 'sysctl
 hw.cpu64bit_capable: 1'

 If the kernel version is less than 10 or the CPU is not 64-bit capable,
 then build 32-bit.
