OK... Per Keith's suggestion I've gone on over to the rsync lists and 
been searching.

http://lists.samba.org/archive/rsync/2006-January/014352.html  clearly 
corroborates our observations that the bug is with OSX and Apple's  
"Mac-specific bug due to their extended-attributes code (at a guess)."

<snipping everything else>

The post goes on to tell of the --itemize  (-i) option on newer versions 
of rsync that will reveal the mystical secrets of why rsync things the 
OSX files are different from the previous backups.    Ok..well maybe not 
mystical secrets..but it should at least be revealing.

I will say this.  Never had I had so much useless success.  I'm just 
elated and thrilled at finally getting finished the workflow and 
procedures that were needed to run these dirvish jobs in the environment 
I've been assigned.  My elation coupled with the current and seemingly 
insurmountable incompatibilities seems to have driven me a little 
loopy.    My wife says I've just gone MAD.  Even so, the little fairies 
and I sit up here with the glow of protons lighting our faces as we 
search for that someone (smarter than us) who can deliver us from the 
evil spell of the forces of JOBS and his wizard, OSXEA.

Yeah...um... I'm gonna go now....  I'll take my dementia to the rsync 
list for a while...
