I don't think it could be an i386 machine, since the kernel has been 
x86_64 only since 10.8. If you see "arch i386" in the platform 
identification line in the log, that just corresponds to the output from 
'uname -p'.

However the reporter is building with +universal, which you can see 
later in the log means x86_64 and i386.

All compilers will define __LP64__ if and only if compiling for a 64-bit 
target. This is correct.
