[imp] Installing IMP on Horde

[Kevjs]

I've just downloaded and installed Horde (version details below)

Horde is located in /var/www/html/horde/

IMP is located in /var/www/html/horde/imp/

/var/www/html/horde/config/registry.php contains :-

$this->applications['imp'] = array(
    'fileroot' => dirname(__FILE__) . '/../imp',
    'webroot' => $this->applications['horde']['webroot'] . '/imp',
    'name' => _("Mail"),
    'status' => 'active',
    'provides' => 'mail',
);

which if i read it correctly means that imp should be located where I 
have it?

However when i move the imp folder to /var/www/html/horde/imp/ i get the 
following error message displayed in the left hand navigation bar when i 
visit http://localhost/horde/

--------------------------------------------------------------------------
Warning: 
main(/var/www/html/horde/services/portal/../../lib/Browser.php): failed 
to open stream: No such file or directory in 
/var/www/html/horde/imp/lib/base.php on line 33
--------------------------------------------------------------------------

Which one would expect as it should be reffering to:
/var/www/html/horde/services/portal/../../imp/lib/Browser.php
                      Note the imp        ^^^^

Is the correct way to resolve this is to move the contents of imp/lib to 
lib or is there another method that should be done?

One thing i have noticed is that  /var/www/html/horde/imp/lib/base.php 
contains


// Find the base file path of Horde
@define('HORDE_BASE', dirname(__FILE__) . '/../..');

// Find the base file path of IMP
@define('IMP_BASE', dirname(__FILE__) . '/..');


which I would expect to refer to

/var/www/html/horde/
and
/var/www/html/horde/imp/

respectivly.  However if you echo these values out you get

/var/www/html/horde/services/portal/../..
/var/www/html/horde/imp/lib/..

Additionally if you comment out the define statements, or change them to 
the paths I would expect you get exactly the same values.

Additionally http://localhost/horde/imp/ returns :-

Some of IMP's configuration files are missing:
html.php     This file controls the stylesheet that is used to set 
colors and fonts in addition to or overriding Horde defaults.
mime_drivers.php     This file controls local MIME drivers for IMP, 
specifically what kinds of attachments are viewable and/or downloadable.
prefs.php     This file controls the default preferences for IMP, and 
also controls which preferences users can alter.
servers.php     This file controls the default settings for IMP, and 
also defines the list

I'm guessing this may be related?

If I issue the command
mv /var/www/html/horde/imp/ /var/www/html/horde/kev_imp/
then the main horde panel starts working correctly, but naturally it 
doesn't have a clue about imp.

Thanks in advance for any help resolving this issue.

VERSION DETAILS
===============

Server is the Apache2 one that comes with Mandrake 10.2/Mandriva 2005LE, 
according to rpmdrake this is 2.0.53-9mdk

Horde Version : Horde: 3.0.5
Horde Applications : Horde: 3.0.5
PHP Version: 4.3.10
PHP Version Classification: release

The tar files used were :
-rw-r--r--  1 root root 3549687 Aug 17 14:20 horde-3.0.5.tar.gz
-rw-r--r--  1 root root 1587465 Aug 17 14:20 imp-3.2.8.tar.gz
-rw-r--r--  1 root root  675796 Aug 17 14:19 pear-1.3.tar.gz

All the statuses in /horde/test.php show "yes" except :

MIME Magic Support (fileinfo): No
The fileinfo PECL module or the mime_magic PHP extension (see below) 
will most likely provide faster MIME Magic lookups than the built-in 
Horde PHP magic code. See horde/docs/INSTALL for information on how to 
install PECL/PHP extensions.

(In this case i have tried 'urpmi php-mime_magic' and get "The 
package(s) are already installed")

and

memory_limit disabled: No
If PHP's internal memory limit is turned on and if not set high enough 
Horde will not be able to handle large data items (e.g. large mail 
attachments in IMP). If possible, you should disable the PHP memory 
limit by recompiling PHP without the "--enable-memory-limit" flag. If 
this is not possible, then you should set the value of memory_limit in 
php.ini to a sufficiently high value (Current value of memory_limit: 8M).

(8M is a sufficient limit as we already restrict users to 3M attachments 
in the current email system)**
