title: Where is config.log Ubuntu 14.04 LTS (gnu/Linux 3.13.0-30-generic *86_64)
body: <p>I tried to install R package "RMySQL" on the R server. 
      <code>Install.packages('RMySQL', type='source')</code><br>
  But there is an error message:</p>
  
  <pre><code>Installing package into ‘/data/rstudio5/R/x86_64-pc-linux-gnu-library/3.0’

  </code></pre>
  
  <p>When I try to find the config.log on PUTTY:
      <code>less config.log</code>
  It says no such file or directory.</p>
  
  <p>Where is the config.log? and how can I check it? There are some related topics on Google but not feasible in this case.
