title: PHP ctype extension not installed (mac)
body: <p>I'm trying to get a base install of Yii running on my mac to do PHP development in the Yii framework.  However, installing Yii requires Composer.  Composer install fails saying that ctype is not installed.</p>
  
  <p>I'm running php 5.5 supplied by AMPPS.</p>
  
  <p>Installing composer:
  curl -sS <a href="https://getcomposer.org/installer" rel="nofollow">https://getcomposer.org/installer</a> | php -- --install-dir=bin</p>
  
  <p>Results in this message:</p>
  
  <p><strong>"#!/usr/bin/env php
  Some settings on your machine make Composer unable to work properly.
  Make sure that you fix the issues listed below and run this script again:
  The ctype extension is missing.
  Install it or recompile php without --disable-ctype
  The openssl extension is missing, which means that secure HTTPS transfers are impossible.
  If possible you should enable it or recompile php with --with-openssl"</strong></p>
  
  <p>I can work with https which would lead me to believe that the openssl message is bogus and the php install manual (<a href="http://php.net/manual/en/ctype.installation.php" rel="nofollow">http://php.net/manual/en/ctype.installation.php</a>) would lead me to believe that ctype is installed and enabled too.</p>
  
  <p>Any ideas on how to fix this?</p>
