title: Installation sphinx + re2 on Arch Linux
body: <p>I need to install sphinx with <a href="http://sphinxsearch.com/docs/current.html#conf-regexp-filter" rel="nofollow">regexp_filter</a> option. 
  I have install <code>re2</code> package with pacman.
  In documentation i see that i can compile the <code>sphinx</code> package with <code>--with-re2</code> option. But when i do this i get error.</p>
  
  <pre><code>checking whether to compile with RE2 library support... configure: error: missing re2 sources
  </code></pre>
  
  <p>Also i've tried to set <code>make</code> options like <a href="http://sphinxsearch.com/bugs/view.php?id=1753" rel="nofollow">here</a>.</p>
  
  <pre><code>--with-re2-libs=/usr/lib/libre2.so --with-re2-includes=/usr/include/re2/
  </code></pre>
  
  <p>but i've got another error</p>
  
  <pre><code>checking whether to compile with RE2 library support... configure: error: missing re2 headers
  </code></pre>
  
  <p>Here my output of <code>ls /usr/include/re2</code></p>
  
  <pre><code>ls /usr/include/re2/
    filtered_re2.h 
    re2.h 
    set.h 
    stringpiece.h 
    variadic_function.h
  </code></pre>
  
  <p>Have anybody install this? Thanks for all help!</p>
