PEAR/MySQL woes: Function registration failed - duplicate name

Installed a new PHP last night because I wanted to start using PEAR. When I use 'pear' from the command line a few funny things happen. Among them are a bunch of errors like the following: PHP Warning: Function registration failed - duplicate name - mysql_connect in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - mysql_pconnect in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - mysql_close in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - mysql_select_db in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - mysql_create_db in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - mysql_drop_db in Unknown on line 0 etc.... I looked in php.ini and the line that includes the mysql.so is only there once: extension=mysql.so Any ideas how I can fix this? I'd rather not have a couple pages full of errors every time I use the pear command. Thanks!!
