  on the <a href="https://stat.ethz.ch/mailman/listinfo/r-sig-finance">R-sig-finance</a> mailing list, but I do not think it has been asked on stackoverflow.</p>
  
  <p>It goes like this:</p>
  
  <p>Where can I obtain the latest version of package XYZ that is hosted on R-forge?  I tried to install it with <code>install.packages</code>, but this is what happened:</p>
  
  <pre><code>&gt; install.packages("XYZ",repos="http://r-forge.r-project.org")
  Warning message: package ‘XYZ’ is not available (for R version 2.15.0)
  </code></pre>
  
  <p>Looking on the R-forge website for XYZ, I see that the package failed to build.
  Therefore, there is no link to download the source.  Is there any other way 
  to get the source code?  Once I get the source code, how can I turn that into a 
  package that I can load with <code>library("XYZ")</code>?</p>
