New include_path after upgrade to 11.5.30 version? php-pear problem

[netsetter]

Just upgraded to Plesk 11.5.30 and found out that sending SMTP emails with php pear aren't working anymore with following error message:

mod_fcgid: stderr: PHP Fatal error: require_once():
Failed opening required 'Mail.php'
(include_path='.:/usr/share/pear')
in /var/www/vhosts/mydomain.com/httpdocs/check.php on line 4

I know in the new Plesk 11.5 are changed structures of all vhosts, but the strange thing is that require_once('System.php') placed into the same directory and file is working correctly with no errors and is returning bool(true), but adding require_once('Mail.php') into the test file is giving me this fatal error.
Well, if you now think that the include_path must be .:/usr/share/psa-pear, well it worked with Plesk 11.09 and stopped working after the upgrade.

Any hints where I could have a look with this mod_fcgid error when

require_once('System.php')

is working but

require_once('Mail.php')

isn't working? Which include path should I use with the new version 11.5.30 ? Or is there another thing now I have to care about?

CentOS 6.4 / PHP 5.3 / php-pear 1.9.4 / Postfix

PEAR bundled with Plesk is not for public use, but is there only for Horde webmail. Therefore it is not recommended to use it, as path to it can change, it's content may be removed or added, or it may be removed in future versions at all. Since Horde was upgraded from 3 to 5, bundled PEAR repository also had to be updated.

Please use your own PEAR installation.
