title: Can't build RStudio IDE with boost 1.56.0
body: <p>I have some problems with building RStudio IDE from the source after updating the 'boost' package to version 1.56.0. </p>
  
  <p>I used following PKGBUILD for Arch Linux package manager: <a href="http://pastebin.com/r1mgj1h2" rel="nofollow">http://pastebin.com/r1mgj1h2</a></p>
  
  <p>Build log with errors: <a href="http://pastebin.com/FjMdxEKA" rel="nofollow">http://pastebin.com/FjMdxEKA</a></p>
  
  <p>Error messages:</p>

  <p>Note: I've built RStudio in the clean chroot described in <a href="https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot" rel="nofollow">this</a> article.</p>
  
  <p>I think that one of the possible solutions would be to install the <code>boost</code> package into separate instance with <a href="https://github.com/rstudio/rstudio/blob/master/dependencies/common/install-boost" rel="nofollow">this</a> script. 
  However it seems very complicated.</p>
  
  <p>Sure that there are a lot of more simple solutions. Any ideas?</p>
