Gaussian 03 on AMD64 and G5's



Hello,
 My apologies if this has been covered at all but the archive search is
 currently having a couple of problems.
 I was wondering if anyone has any experiences they're willing to share
 (good or bad) with getting Gaussian 03 running on an AMD64 platform or
 on an apple G5 (in a 64-bit environment)?
 I will summarise for posterity if there's enough interest.
