Mac OSX 32bit or 64bit
I followed this article... http://support.apple.com/kb/HT3696 and found that 

    Processor name: IntelCore i7 

meaning it is 64 bit.

However, when I do **"uname -a"** in terminal the result seem to be contradictory.

    MYMACHINE:~ himalay$ uname -a
    Darwin MYMACHINE 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun  7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386

Also thru perl its the same.. 

    MYMACHINE:~ himalay$ perl -V:myarchname
    myarchname='i386-darwin';


i386 is 32bit as far as I know. Can someone clarify on this. Thank you.
