[imp] Strange problem

[Tommaso Leonardi]

Hi list,
I upgraded Horde and imp from version 2 to the latest.
Horde had no problems, was working well. So, I decided to install also imp. Now, when I
visit Horde's page, I get this error:

| Warning: main(/home/web/itm5/horde/lib/Browser.php): failed to open stream: No such file
or directory in /home/web/itm5/horde/imp/lib/base.php on line 18
|
| Fatal error: main(): Failed opening required '/home/web/itm5/horde/lib/Browser.php'
(include_path='/home/web/itm5/horde/lib:.:/usr/local/lib/php') in
/home/web/itm5/horde/imp/lib/base.php on line 18

And when i visit horde/imp I get a blank page.

I've looked the error up over the internet, both on Horde's site, and on google without
any result.
So, I've created an empty Browser.php file in horde/lib, and i got this:
|
| Warning: main(/home/web/itm5/horde/lib/Registry.php): failed to open stream: No such
file or directory in /home/web/itm5/horde/imp/lib/base.php on line 40
|
| Fatal error: main(): Failed opening required '/home/web/itm5/horde/lib/Registry.php'
(include_path='/home/web/itm5/horde/lib:.:/usr/local/lib/php') in
/home/web/itm5/horde/imp/lib/base.php on line 40

I did the same for Registry.php, Auth.php, Secret.php, Prefs.php and Help.php

As I expected, I got an error message saying that a library was missing:
| Call to undefined function: getmethod() in /home/web/itm5/horde/imp/lib/base.php on line 64

Can somebody help me? I'm pretty sure this is stupid problem, but I can't understand where
the solution is...

Thankyou in advance,
Tommaso Leonardi
