So, does the script actually work on the AMD system? I'm guessing no, but you didn't say. Have you verified that your script didn't get corrupted during the transfer? Have you verified that perl is correctly installed on the AMD machine?

I'm fairly certain AMD based XP versions of activestate perl are tested in the same way that Intel based versions are tested, so I'm doubting there is a Perl specific bug with AMD based systems...

Update: Oooo! Did you perhaps grab a non-AMD binary version of Perl and install that on the AMD machine?

Update: Never mind, Active state doesn't appear to care whether the machine is AMD or Intel based...
