And I just realised that you indeed have two disconnected PEAR  
installations. Most likely you'll also want to change the php_dir so  
that the system and user configurations for all of the above  
parameters match. Since your Apache user doesn't use a separate PEAR  
configuration, it is probably best to set

      pear config-set ext_dir   /usr/lib64/php/modules system
      pear config-set horde_dir /var/www/html/horde system
      pear config-set man_dir   /usr/share/man system


      pear config-set php_dir   /usr/share/pear <- note the absence of  
system here!

After that, you'll need to upgrade all Horde packages again, since  
you've switched to the system setup. If you don't have specific  
requirements about separate PEAR installations for different setups, I  
would skip the last step and just remove the .pearrc file for the root
