Eu tive o mesmo problema. Você deve reconfigurá-lo para encontrar os pacotes PEAR.
Substitua a versão do PHP do Mac OS X pela MAMP
$ cd /usr/bin
$ cp php php.bak (Backup the old version)
$ ln -s /Application/MAMP/bin/php5.3/bin/php (link to the version of MAMP php)
$ sudo chmod 0554 /Application/MAMP/bin/php5.3/bin/* (makes all the scripts executable)
$ php -v
