horde-2.1-3.noarch.rpm
imp-3.1-2.norach.rpm
already have apache 1.3.27 installed and running with the following for the
virtual host to be used with horde
<VirtualHost 172.31.14.31:8000>
DocumentRoot /usr/local/apache/htdocs/horde

</VirtualHost>
but when I go to the page 172.31.14.31:8000/index.php
it just gives me a blank page and the following is logged in the
apache logs:

[Thu Dec 12 12:21:57 2002] [error] PHP Fatal error:  Call to undefined function:  _() in /usr/local/apache/htdocs/horde/templates/index/notconfigured.inc on line 4
 and if I goto 172.31.14.31:8000/test.php the following is logged
with a blank p[Thu Dec 12 12:23:39 2002] [error] PHP Warning:  Failed opening '/usr/local/apache/htdocs/horde/test.php' for inclusion (include_path='/usr/share/php:/usr/share/pear:.') in Unknown on line 0

Any help would be greatly appreciate,
