title: Mac SVN E175002: Could not resolve hostname `'
body: <p>I'm getting "Could not resolve hostname `' " for any hostname I enter that uses the http/https protocol. No matter what hostname I use it returns the backtick single quote. DNS works fine, I can ping the domain, and navigate to the repo using a browser. I can also browse the repo using TortoiseSVN on a windows machine.</p>
  
  <pre><code>svn: E175002: OPTIONS of 'http://mysite.com/svnrepo': Could not resolve hostname `': Host not found (http://mysite.com)
  svn: E175002: OPTIONS of 'http://nonexistantdomain': Could not resolve hostname `': Host not found (http://nonexistantdomain)
  </code></pre>
  
  <p>If I use the svn:// protocol the hostname resolves just fine. I've tried using the svn that ships with Mac OS X 10.8 Mountain Lion, SVN from Ports, WANDisco, I even compiled the source and I'm still getting the same thing. I also downloaded serf-1.1.1 and compiled that.</p>
  
  <p>I can't figure out how svn resolves the host name.</p>
