In your second log file I found some strange messages:
D [27/Jun/2011:14:02:57 -0400] [Job 520042] Updating PageSize to [271 136]...
which seems to be correct, but some messages later:
D [27/Jun/2011:14:02:57 -0400] [Job 520042] Updating PageSize to [612 792]...
which means Ghostsdcript's cups device forgot the correct page size and reverted
to the default letter page size.

To further trace it down I'd need the repsective PPDs from both machines.
