Squirrelmail problem

[Brent]

Got a problem when trying to open emails:

Warning: main(DB.php): failed to open stream: No such file or directory in /usr/share/squirrelmail/plugins/sasql/sasql_db.php on line 5

Fatal error: main(): Failed opening required 'DB.php' (include_path='.:') in /usr/share/squirrelmail/plugins/sasql/sasql_db.php on line 5

I have installed php-pear via yum install php-pear

I try to run pear install db and get this:

pear install db

Warning: main(Console/Getopt.php): failed to open stream: No such file or directory in System.php on line 27

Fatal error: main(): Failed opening required 'Console/Getopt.php' (include_path='/usr/share/pear') in /usr/share/pear/System.php on line 27


What am I doing wrong?
