Please always repeat everything every time; don't delete content from 
threads.

I'm travelling and cannot handhold.

Build only from source, only one piece at a time, and check everything 
every time. I'm sure that other people have seen dependency problems when 
installing from binary on this platform. This is not seen on any other 
platform (Linux, Windows, OSX). There are two underlying problems: 
"dependency hell" and your inability to sort out your own system. I 
suspect that the XML package in R does not have its dependencies 
satisfied. It could also be GDAL/GRASS not having dependencies satisfied. 
The reason to build from source is that then you control the dependencies, 
rather than the reverse.

Please stop creating the impressionn that software that works for 
effectively everyone else is broken only because you can't get your own 
system to work, and expect others to do your work for you!
