title: 'rbenv install 2.0.0-p247' fails
body: <p>i already discussed this issue with the maintainer of ruby-build and followed his advice by googling for similar errors. i found similar ones but they do not seem to match my specific problem:</p>
  
  <p>i'm trying to install ruby with <code>rbenv install 2.0.0-p247</code> (using the ruby-build plugin) on archlinux – but the command fails.</p>
  
  <p>here the last 10 log lines:</p>
  
  <pre><code>rbconfig.rb updated
  generating enc.mk
  compiling dln.c
  compiling encoding.c
  generating prelude.c
  compiling prelude.c
  linking static-library libruby-static.a
  verifying static-library libruby-static.a
  collect2: error: ld returned 1 exit status
  make: *** [libruby-static.a] Error 1
  </code></pre>
  
  <p>i would appreciate any hints on this problem – thanks!</p>
