Ubuntu 10.04 LTS Perfect Server PEAR.php problem

Hi

I have a application that requires PEAR.php
And I get this error in log:
[warn] [client xxx.xx.50.23] mod_fcgid: stderr: PHP Fatal error:
>> require_once(): Failed opening required 'PEAR.php'
>> (include_path='.:/usr/share/php:/usr/share/pear') in

What may be the problem here.
I have followed the how to carefully, and double checked.

 

Bumping this...
Anybody been through this before?

 

Try with apt-get install php-pear

Or

apt-get purge php-pear; apt-get install php-pear

Cheers

 

ispconfig 3.0.4.1
debian 6.0.3
pear is under /usr/share/php
but in vhost file i see:

Code:

php_admin_value open_basedir /var/www/clients/client4/web9/web:/var/www/clients/client4/web9/tmp:/var/www/xxxxxx/web:/srv/www/xxxxxx/web:/usr/share/php5:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin

relevat is: :/usr/share/php5:

can i change default location?
instead of /usr/share/php5 i would have /usr/share/php

 

You can change it or add /usr/share/php.
