[haghighi]

Hey
my freeradius works fine in Command, thus i install daloradius(web UI) and configure it correctly. when i run localhost/daloradius and insert username and password it dosent work! :(
this is error page contents:

Warning: include_once(DB.php): failed to open stream: No such file or directory in /usr/local/www/daloradius/library/opendb.php on line 84 Warning: include_once(): Failed opening 'DB.php' for inclusion (include_path='.:/etc/inc:/usr/local/www:/usr/local/captiveportal:/usr/local/pkg') in /usr/local/www/daloradius/library/opendb.php on line 84 Fatal error: Class 'DB' not found in /usr/local/www/daloradius/library/opendb.php on line 86

I installed 'php5-gd' correctly but still have problem with two others
How to install 'php-pear' and 'php-db'?
