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/ ApplicationServices.framework/Versions/A/Frameworks/ ImageIO.framework/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.
Ding! I get it. It is a problem with the case independent file system. libJPEG would be different from the gnu libjpeg, but on HFS+ it is not. Hence the confusion. I will try to look at it later. I think all I may need to do is remove the libjpeg.dylib symlink, which would Appleise it. Bill
