I will have access to an OSX laptop in a little over a week, and will try 
out the CRAN rgdal binaries. Just one report of installation failure isn't 
enough. I think that maybe someone on R-sig-mac might know why rgdal.so is 
looking for libR.dylib; I don't use OSX, and don't have easy access to 
such a machine, which is why I asked for others to comment.
