You must include all of the important information: all of sessionInfo() 
output, all of the startup messages given by rgdal on loading, and a 
reasonable example (this one isn't, the actual projection is unknown). I 
think you have installed rgdal from source on a system without the 
necessary extra files, but without knowledge of how you installed rgdal, 
it is not possible to tell.
