[horde] include path

[Jānis]

Hi!

I m trying to install horde (5.1.6) inseparate directory using
#pear config-create /home/htdocs/horde5 /home/htdocs/horde5/pear.conf
#pear -c /home/htdocs/horde5/pear.conf install pear
#/home/htdocs/horde5/pear/pear -c /home/htdocs/horde5/pear.conf  
channel-discover pear.horde.org
#/home/htdocs/horde5/pear/pear -c  /home/htdocs/horde5/pear.conf  
install horde/horde_role
#/home/htdocs/horde5/pear/pear -c  /home/htdocs/horde5/pear.conf  
run-scripts horde/Horde_Role

with follwing
/home/htdocs/horde5/pear/pear -c  /home/htdocs/horde5/pear.conf  
install -f horde/horde-5.1.6.tgz
etc.

but in the end I get :
HP Fatal error:  require_once(): Failed opening required  
'Horde/Autoloader/Default.php'  
(include_path='/home/htdocs/horde5/lib:.:/usr/lib64/php') in  
/home/htdocs/horde5/lib/core.php on line 47

Unfortunately, Horde's INSTALL is quite cryptic on how to point the  
include_path to /home/htdocs/horde5/pear/php where the stuff resides.

putting it into php.ini does not help
