It's a problem in your library setup. Your /usr/local/lib/ 
libJPEG.dylib conflicts with the system libJPEG.dylib from ImageIO  
framework (which is in /System/Library/Frameworks/ 
Versions/A/Resources/libJPEG.dylib). Since R forces the load of the  
one in /usr/local/lib first (as you configured it), it is loaded  
instead of the one in ImageIO framework, but it doesn't contain the  
same symbols, thus the load fails. You should remove /usr/local/ 
libJPEG.dylib and use static version or ImageIO instead.
