title: GenomicFeatures Package Installation Trouble
body: <p>Sorry to be back so soon with a simple installation question, but my inability to solve it myself is seriously impairing my productivity. Anyway, I tried installing GenomicFeatures as suggested by the BC website.</p>
  
  <pre><code>&gt; source("http://bioconductor.org/biocLite.R")
  &gt; biocLite("GenomicFeatures")
  </code></pre>
  
  <p>I received the following error messages (in addition to several warning messages)</p>
  
  <pre><code>ERROR: configuration failed for package ‘RCurl’
  * removing ‘/home/tim/R/i686-pc-linux-gnu-library/2.15/RCurl’
  ERROR: dependencies ‘XML’, ‘RCurl’ are not available for package ‘rtracklayer’

  <p>So some problem with the dependencies I guess, but it seems strange that they would be automatically installed prior to GF. I am using version 2.15.0. Any clue as to what the problem might be? I'd be happy to provide more info as needed. Thanks.</p>
