title: Installation of RODBC/ROracle packages on OS X Mavericks
body: <p>I have been trying to install some packages such as RODBC, ROracle or RGtk2 - used for rattle.  I would really appreciate it if someone could help me get around this problem so that I could use these applications on a Mac with mavericks and with 3.1.1 R</p>
  
  <p>I get this sort of error for both RODBC and RGtk2:</p>
  
  <blockquote>
    <p>package ‘RGtk2’ is available as a source package but not as a binary
    Warning in install.packages :   package ‘RGtk2’ is not available (for
    R version 3.1.1)</p>
  </blockquote>
  
  <p>When I try to use type='source', I can download or start to download  but then I get this sort of error message...</p>
  
  <p>Warning in install.packages :
    installation of package ‘RODBC’ had non-zero exit status</p>
