I've downloaded the libs from the above site, yet I still 
get the following msg from horde/test.php.
This version of PHP is supported but the PEAR library that comes with this
version is not recent enough. See <http://horde.org/pear/> for details.
Horde requires at least PHP 4.0.5 and PEAR 4.0.7.
I've untarred into /usr/local/lib/php, first moving the old one to
/usr/local/lib/php.old
