Can't Add New Horde Module

[fredb]

Some new Horde modules requires DOMXML or DOM

I can’t add additional Horde modules because of the following error:

==============
A fatal error has occurred
You need the domxml or dom PHP extension to use the configuration tool.
[line 25 of /usr/local/interworx/lib/horde/admin/setup/config.php]
==============

Can the domxml extension be installed on the Interworx Control Panel - PHP install?

Are there any workarounds?

Thank

Fred

I know it's been some time since a response, but just wondering if you got this resolved. This *should* do the trick: yum install php-domxml
