R problem (fwd)

The error message from R when I try to load grDevices (it seems  
that it has a probelm with some jpeg stuff - which I also find kind  
of odd since capabilities(jpeg) is FALSE)

By default R before 2.1.1 added /usr/local/lib to DYLD_LIBRARY_PATH  
which overrides the search sequence for dynamic libraries.

You will have to remove /usr/local/lib/libjpeg.dylib because it  
conflicts with system's ImageIO framework - it should be a just a  
symlink anyway so it shouldn't affect other applications. (see http:// 
wiki.urbanek.info/index.cgi?TigeR for details) This is fixed in R 2.1.1.

Cheers,
