[R-sig-Debian] Problem installing some packages on Ubuntu 7.10

[Brian Lunergan]

Evening all:

Recently moved over to Ubuntu 7.10. Installed version 2.7.0 of R from 
the U of T site in Ontario, Canada. Working on installing Rcmdr as my 
GUI of choice (yes, I know lots of you probably prefer an emacs/ess 
combination but give me a break. It's what I was comfortable with using 
R under XP). For the most part the installs have gone well in a regular 
terminal window using sudo R or just R in a root terminal window, but 
some of the packages just don't seem to be going quietly.

I could use some advice as to what I might need to add to my setup or 
correct to get things to install. I'll deal with them one at a time so I 
can follow through on any suggestions offered before moving on to the 
next troublemaker. There are six involved, some of them being key 
players in the desired setup. First up is XML. I've included everything 
install.package() spit out to avoid confusion. My apologies if it's TOO 
much, but I'm no programmer so I didn't want to error by cutting 
something out that might have turned out to be useful.
