Needed to install PEAR on Lion, as my laptop hadn’t yet needed it. Wanted to see fi there was a way within Lion, and discovered the instructions.
sudo cp /private/etc/php.ini.default /private/etc/php.ini php /usr/lib/php/install-pear-nozlib.phar pear config-set php_ini /private/etc/php.ini pecl config-set php_ini /private/etc/php.ini sudo pear upgrade-all
Works fine for me, except I need to do this commands as root (sudo )
