title: Installing/enabling PHP Pecl Intl extension on a default Mac OS X Leopard bundled PHP configuration
body: <p>How can I install or enable the PHP Pecl Intl extension in my PHP environment?</p>
  
  <p>I've got a stock PHP configuration that came bundled with Mac OS X Snow Leopard.
  Installing libicu from source and than <code>$pecl install intl</code> results in the following error:</p>
  
  <pre><code> /private/tmp/pear/temp/intl/collator/collator_class.c:92: error: duplicate 'static'
   /private/tmp/pear/temp/intl/collator/collator_class.c:96: error: duplicate 'static'
   /private/tmp/pear/temp/intl/collator/collator_class.c:101: error: duplicate 'static'
   /private/tmp/pear/temp/intl/collator/collator_class.c:107: error: duplicate 'static'
   make: *** [collator/collator_class.lo] Error 1
   ERROR: `make' failed
  </code></pre>
  
  <p>Any help is really appreciated!</p>
