Thanks Brian, thanks everybody. I think I can easily understand the difficulties you are speaking about: R is a huge project running in a massive amount of different, and from time to time, fancy environments. I is by no means easy to keep all packages smoothly running in all and every installation around the World! For me, maintaining CRAN is a big responsibility and of extreme difficulty!

But I'm not able to understand yet what is the difference between using the R Package Installer (using CRAN repository as package repository), running in this case R Mac OS X 10.5.8  with this R installation...

R version 2.15.1 (2012-06-22) -- "Roasted Marshmallows"
Copyright (C) 2012 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

And downloading XML_3.9-4.tgz from http://cran.r-project.org/web/packages/XML/index.html and installing it by submitting sudo R CMD INSTALL XML_3.93-0.tgz.

The process using R Package Installer (CRAN binaries as repositoy) doesn't lead to a functional XML packages and downloading and installing it does lead to running XML packages both in i386 and x86_64 architectures.

Sorry for asking once again, but, please, where am I lost with this issue?

Thanks!
