** WARNING! Old version found at /usr/local/php5/bin, please remove it or be sure to use the new /usr/local/php5/bin/pear command
The ‘pear’ command is now at your service at /usr/local/php5/bin/pear
** The ‘pear’ command is not currently in your PATH, so you need to
** use ‘/usr/local/php5/bin/pear’ until you have added
** ‘/usr/local/php5/bin’ to your PATH environment variable.
Run it without parameters to see the available actions, try ‘pear list’
to see what packages are installed, or ‘pear help’ for help.
