[horde] Horde 3.0.4 from OpenBSD ports doesn't work!

[snoop@email.it]

I've built Horde from latest stable OpenBSD 3.8 ports. The release is 3.0.4.
I've followed step by step the installation/configuration (and database creation) guide.
I'm using PostgreSQL server v.8.0.4 built from the same ports tree (and work perfectly).
I've built all from the same ports tree and is in sync with the kernel release ...
... all running on a dual athlon 2000+ but I don't think it's a relevant info.

If I enable datatree I display this message on browser:
"A fatal error has occurred
DB Error: connect failed
Details have been logged for the administrator."

1:anything was logged on /tmp/horde.log and the file doesn't exist
2:horde never try to connect to my postgresql server

If I disable datatree uncommenting (in the config file appended below)
$conf['datatree']['driver'] = 'null';

and commenting

$conf['datatree']['params']['phptype'] = 'pgsql';
$conf['datatree']['params']['persistent'] = false;
$conf['datatree']['params']['port'] = 5432;
$conf['datatree']['params']['protocol'] = 'tcp';
$conf['datatree']['params']['hostspec'] = 'localhost';
$conf['datatree']['params']['username'] = 'horde';
$conf['datatree']['params']['password'] = '************';
$conf['datatree']['params']['database'] = 'horde';
$conf['datatree']['params']['charset'] = 'iso-8859-1';
$conf['datatree']['params']['driverconfig'] = 'custom';
$conf['datatree']['driver'] = 'sql';

(it's the same result that disabling datatree from web configurator)
I open the login screen, but if I use a correct or uncorrect 
username/password I've been automatically redirected to www.horde.org.
Login on imp it's the same but I've been redirected to www.microsoft.com !!!
Anything of useful are logged by horde!!! :-@

I know that my english it's not so good but I think I have been clear.
I hope that someone can help me!
Thanks a lot.

P.S. On OpenBSD ports Horde is "chained" to php 5.0.4 and isn't possible to build it with php 4.x.
