Hi,
i have installed horde on my Linux Mandrake 8.0 server and when i look the 
http:/myserver/horde/test.php page i obtain the following output:

        Log - No
        Make sure you're using a recent version of PEAR which includes the Log
class.
        DB - Yes

My question is, what should i do to enable the Log capability of Pear?
When i try to log in IMP i obtain error message about the 
horde/lib/Horde.php and i think the problem is related with the Pear Log no 
state.

In addition I'm using postgresql 7.2.1 , apache 1.3.24 and imap-2001a


Thanks in advance.
