[imp] incorrect installation?

[Lito A. Lampitoc]

After following all the instructions in the INSTALL file, I managed to
install all the prerequisites of IMP. but when accessing 
mydomain.com/horde/imp my browser return the content of index.php like
this one:
-----------------

 */ define('IMP_BASE', dirname(__FILE__));
$imp_configured = (@is_readable(IMP_BASE . '/config/conf.php') &&
                   @is_readable(IMP_BASE . '/config/html.php') &&
                   @is_readable(IMP_BASE . '/config/mime_drivers.php')
&&
                   @is_readable(IMP_BASE . '/config/prefs.php') &&
                   @is_readable(IMP_BASE . '/config/servers.php')); if
($imp_configured) {
    include_once IMP_BASE . '/lib/base.php';
   
    $uri = 'redirect.php';
    if (!empty($HTTP_SERVER_VARS['QUERY_STRING'])) {
        $uri .= '?' . $HTTP_SERVER_VARS['QUERY_STRING'];
    }
   
    header('Location: ' . Horde::applicationUrl($uri, true));
    exit;
   
/* IMP isn't configured */
} else {
    include IMP_BASE . '/templates/index/notconfigured.inc';
} ?>

I think my apache support php4 because i compiled with php support
statically and doing httpd -l:

Compiled-in modules:
  http_core.c
  mod_env.c
  mod_log_config.c
  mod_mime.c
  mod_negotiation.c
  mod_status.c
  mod_include.c
  mod_autoindex.c
  mod_dir.c
  mod_cgi.c
  mod_asis.c
  mod_imap.c
  mod_actions.c
  mod_userdir.c
  mod_alias.c
  mod_access.c
  mod_auth.c
  mod_so.c
  mod_setenvif.c
  mod_php4.c
suexec: disabled; invalid wrapper /usr/local/apache/bin/suexec

mod_php4.c is enabled.

accessing mydomain.com/horde has the same effect.

What do you think I am missing here?  Any help is greatly appreciated.

Thank you.
