title: Error installing R 2.13.0 packages (caret) on Ubuntu 10.04
body: <p>I have R installed via the CRAN repo as instructed at <a href="http://cran.r-project.org/bin/linux/ubuntu/" rel="nofollow">http://cran.r-project.org/bin/linux/ubuntu/</a>. I've been able to install caret fine on a couple other identical Ubuntu 10.04 systems in the past, but today <code>install.packages('caret', dependencies=c('Depends','Suggests'))</code> resulted in the following errors (just a sample).  Any hints?</p>
