title: pear install on mamp 3.0.
body: <p>I am trying to install PEAR on fresh install of MAMP 3.0.  OSX 10.8.5
  So far I </p>
  
  <p>1) Changed the directory permissions so I can execute files within them chmod 774 /Applications/MAMP/bin/php/php5.5.9/bin/pear</p>
  
  <p>2) Setup an alias to avoid typing the whole path.
  alias mpear="/Applications/MAMP/bin/php/php5.5.9/bin/pear"</p>
  
  <p>3) I checked whether pear is working by:
  mpear –V
  It all seems OK:
  PEAR Version: 1.9.4
  PHP Version: 5.5.9
  Zend Engine Version: 2.5.0</p>
  
  <p>4) Next I tried to upgrade pear:
  mpear channel-update pear.php.net 
  and the response I got on Terminal is
  channel-add: temp_dir is not writable: "/tmp/pear/install" - You can change this location with "pear config-set temp_dir"
  So I am stuck there… Can someone help with config-set – what exactly I need to enter into the Terminal.</p>
