This is a completely clean, fresh install. I've not installed any peculiar
libraries or packages, except R, the installation of which still puzzles
me.
I configured a CRAN mirror for packages using squeeze-cran3 folder, and
that's where the first funny thing happened. I noticed same when R-2.15.3
came out, but I thought I had this trouble because my system was all junked
up with unusual libraries. But now, on a clean system, I get this error,
which indicates I need a package liblzma2, which does not exist in Debian:
The following packages have unmet dependencies:
r-base-core : Depends: liblzma2 (>= 4.999.9beta+20091116) but it is not
installable
Recommends: r-recommended but it is not going to be installed
Recommends: r-base-dev but it is not going to be installed
Recommends: r-doc-html but it is not going to be installed
