[imp] IMP installation

[Sergio Ramírez]

Hi

I have installed IMP 3.2.8 over Horde 3.1.3 over PHP 5.1.6

When I run the mainpage of IMP (http://my-server/horde/imp/test.php), I 
have the following error message:
*
Warning*: 
require_once(/usr/local/webmail05/apache/htdocs/horde-3.1.3/admin/../lib/Browser.php) 
[function.require-once 
<http://dispendio.upc.es:8080/horde-3.1.3/admin/function.require-once>]: 
failed to open stream: No such file or directory in 
*/usr/local/webmail05/apache/htdocs/horde-3.1.3/imp-3.2.8/lib/base.php* 
on line *25*

*Fatal error*: require_once() [function.require

in 
*/usr/local/webmail05/apache/htdocs/horde-3.1.3/imp-3.2.8/lib/base.php* 
on line *25

*I have found the file Browser.php, but it isn't in the path where IMP 
is searching it.
How I solve this problem whithout changing the php code of base.php or 
coping Browser.php to another path?
Is there a problem with te configuration?

Thank you.
