Installing Horde 3 & IMP 4

[Roger Grosswiler <roger@xxxxxxxx>]

Hi,

i try to install Horde 3 & IMP 4 on my webserver, this requires from php:

b. XML and DOMXML support. ``--with-xml --with-dom``

      Horde's help engine and component configuration require XML
      support. While some webservers (including recent Apache 
versions) 	      have XML libraries built-in, others will require the 
expat XML parser
      libraries, available from
        http://expat.sourceforge.net/

      .. Important:: You must have **both** XML libraries installed for 
Horde to work properly!

doing rpm -q expat, this gives me:
expat-1.95.7-1.1

nevertheless, i get errors, that xml is not supported:
(from /horde/test.php)

DOM XML Support: No


...do you have any idea, which config i would have to change, so xml is 
recognized?

Thx,
Roger
