title: RVM install issue - Unable to execute port (autoconf)
body: <p>I'm trying to install Jekyll on OSX mountain lion. First of all I wanted to install RVM and then the latest ruby. However, the RVM install is failing and I can't solve the problem. Any help appreciated</p>
  
  <p>Here is what I did:</p>
  
  <ul>
  <li>Installed OSX Command Line Tools</li>
  <li>Attempted to install RVM (<code>\curl -L https://get.rvm.io | bash -s stable --ruby</code>) but it failed with an error in the log "Error: Please install Xcode and/or run xcode-select to specify its location."</li>
  <li>Installed XCode to see if that would help (realise now I could have used xcode-select oh well)</li>
  <li>Attempted to install RVM again but it failed again, see error below</li>
  </ul>
  
  <p><strong>Last lines of install output including error:</strong></p>
  
  <p>Installing required packages: autoconf, automake, libtool, pkgconfig, apple-gcc42, libiconv, libyaml, libffi, readline, libxml2, libxslt, libksba, openssl, curl-ca-bundle, sqlite3, zlib, gdbm, ncurses...</p>

  <p>I opened the error log and it states:</p>
  
  <p><strong>Error: Unable to execute port: Could not open file: /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/devel/autoconf/Portfile</strong></p>
  
  <p>This is probably obvious to someone else but frankly I'm not sure what I'm supposed to do to fix it!</p>
