One final note to anyone that comes across this later.  KDE-4.4 stuff 
also calls: "libjpeg.so.*" directly without going through Qt which I did 
not consider and which was the cause of a great deal of confusion.  So, 
what I needed to do after upgrading JPEG was to see that both Qt and my 
KDE-4.4 BRANCH tree rebuilt correctly.  Obviously although I did the 
rebuilds, it didn't work automatically.
