ISPConfig needs DOM-XML php-extension/module for RoundCube

What Version are you running, please? I'm wondering where you found this line of code:

'./configure' '--with-apxs=/root/ispconfig/httpd/bin/apxs' '--enable-track-vars' '--enable-sockets' '--enable-mbstring=all' '--with-config-file-path=/root/ispconfig/php' '--enable-ftp' '--prefix=/root/ispconfig/php' '--with-openssl=/root/ispconfig/openssl' '--with-mysql=/usr' '--disable-libxml' '--disable-dom' '--disable-xml' '--disable-xmlreader' '--disable-xmlwriter' '--disable-simplexml' '--without-pear' '--with-mcrypt=/root/ispconfig/libmcrypt'

As I can not find this at all…

Cheers

Ok, figured the switch is only there to check whether the "libxml2 stuff" is installed and in case it isn't it'll use the string "WITH_XML="--disable-libxml …"
In my case I uninstalled the libxml2-dev and then reinstalled it again with

apt-get install libxml2-dev

and for the sake of it, a reboot on top. After this I reinstalled ISPConf 2.2.27 out of the box — no mods anywhere! — and finally got the "libXML support active" showing in the

phpinfo();
