[horde] horde problem

[zafar]

hello sir
 i am using qmai with vpopmail. and without any database support ,i mean i
am using cdb file system for authentication.
i wan to configure horde but can't succeeded
sir plz tell me where i am wrong. i test the page so get that
errors , i change nothing in that files so what i do change in these files.
      Some of Horde's configuration files are missing:
      horde.php This is the main Horde configuration file. It contains paths
and basic items that apply to the core framework and all Horde applications.
      html.php This file controls the stylesheet that is used to set colors
and fonts for the Horde framework and all applications that do not provide
their own settings.
      mime_drivers.php This file controls the global set of MIME drivers for
the Horde framework, allowing applications to make use of programs such as
enscript or mswordview to render content into HTML for viewing in a browser.
      mime_mapping.php This file maps file extensions to logical MIME types,
enabling Horde applications to figure out how to handle some content such as
email attachments or CVS checkouts.
      registry.php The registry is how Horde applications find out how to
talk to each other. You should list any installed Horde applications that
you have here.

so how i remove it or what changes i do in these file....
thanks
