[erlang-bugs] 64-bit compile fails on Snow Leopard

Reboot and hold down the 6 and 4 keys on your keyboard. If your mac  
has a new enough CPU, it will boot up with the 64-bit kernel instead  
of the standard 32-bit kernel. The bug I'm reporting wouldn't  
typically be seen in normal use, but it is still wrong to assume non- 
i386 means ppc, which is what the check is probably there for.
