title: R v3.4.0-2 unable to find libgfortran.so.3 on Arch
body: <p>I was just on vacation for a month so am unable to say the exact point at which this happened, but <code>R</code> from the official Arch repos is now unable to start, citing </p>
  
  <pre><code>/usr/lib64/R/bin/exec/R: error while loading shared libraries: 
  libgfortran.so.3: cannot open shared object file: No such file or directory
  </code></pre>
  
  <p>I thought that perhaps a symlink was improperly placed or destroyed, so I looked in /usr/lib to try to find it:</p>
  
  <p><code>ls -halt /usr/lib/libgfortran.so.*</code></p>
  
  <pre><code>lrwxrwxrwx 1 root root   20 May 16 03:01 /usr/lib/libgfortran.so.4 -&gt; libgfortran.so.4.0.0
  -rwxr-xr-x 1 root root 7.1M May 16 03:01 /usr/lib/libgfortran.so.4.0.0
  </code></pre>
  
  <p>Has <code>libfortran.so.3</code> been superseded by <code>libgfortran.so.4</code> in Arch?  If so, are there any possible workarounds for getting <code>R</code> to run with an older version? </p>
  
  <hr>
  
  <p><code>pacman -Qi r</code></p>

  <p>Edit: If anyone else comes across this, the <a href="https://aur.archlinux.org/packages/r-devel/" rel="noreferrer">r-devel</a> AUR correctly compiles and runs, so hopefully on the next version bump the issue will be resolved. </p>
