WHMCS built-in module OpenSRS: Fatal error: Undefined constant 'MCRYPT_DEV_URANDOM'

[Eric Pretorious]

When accepting a domain name order in WHMCS and send the domain name to the registrar (using the WHMCS built-in OpenSRS module) WHMCS complains:

Fatal error: Undefined constant 'MCRYPT_DEV_URANDOM' in /var/www/vhosts/.../httpdocs/whmcs/modules/registrars/opensrs/opensrs.php on line 0

I've checked WHMCS Utilities -> System -> PHP Info and mcrypt is not being loaded even though I've downloaded+installed the third party classes to the /modules/registrars/opensrs/ directory (as detailed in the section "Additional Registrar Module Files Requirement" of the WHMCS doc "OpenSRS").

Have I overlooked a setting somewhere [in Plesk or in WHMCS]?

WHMCS ver 5.2.2
Plesk ver 11.0.9 (Linux)

FTR: The php-mcrypt package is available (for Centos, Scientific Linux, and Oracle Linux administrators) from the RPMforge repository (a.k.a. Dag's repository) and from the EPEL repository. To add the RPMforge repo to your Centos, Scientific Linux, or Oracle Linux system...

======================= N/S Matched: php-mcrypt =======================
php-mcrypt.x86_64 : Standard PHP module provides mcrypt library support

Installing the php-mcrypt package does not quite fix the problem, however, because even though the package contains the module Apache does not load the module:

[root@www ~]# rpm -ql php-mcrypt
[COLOR="#00FF00"]/etc/php.d/mcrypt.ini
/usr/lib64/php/modules/mcrypt.so[/COLOR]

[root@www ~]# cat /etc/php.d/mcrypt.ini 
; Enable mcrypt extension module

[root@www ~]# apachectl -t -D DUMP_MODULES | grep php

[root@www ~]# apachectl -t -D DUMP_MODULES | grep crypt

In order to force Apache to load the mcrypt.so module, I had to modify the mcrypt.ini file, restart Apache, and check the output of the phpinfo() subroutine:

[root@www ~]# cat /etc/php.d/mcrypt.ini 
; Enable mcrypt extension module
[COLOR="#FF0000"]extension=module.so[/COLOR]

[root@www ~]# wget -qO- http://rocket-powered.com/info.php | grep -i mcrypt
/etc/php.d/mcrypt.ini,

[root@www ~]# vi /etc/php.d/mcrypt.ini

[root@www ~]# /etc/init.d/httpd restart

Starting httpd:                                            [  [COLOR="#00FF00"]OK[/COLOR]  ]

[root@www ~]# cat /etc/php.d/mcrypt.ini

[root@www ~]# apachectl -t -D DUMP_MODULES | grep crypt
