1 get go-pear.php from http://pear.php.net/go-pear 2 edit that file so that the lines pointing to the bootstrap files (around line 115) become {{ $bootstrap_files = array( 'PEAR.php' => 'http://svn.php.net/viewvc/pear/pear-core/branches/PEAR_1_4/PEAR.php?view=co&pathrev=319707', 'Archive/Tar.php' => 'http://svn.php.net/viewvc/pear/packages/Archive_Tar/tags/Archive_Tar-1.3.7/Archive/Tar.php?view=co&pathrev=325163', 'Console/Getopt.php' => 'http://svn.php.net/viewvc/pear/pear-core/branches/PEAR_1_4/Console/Getopt.php?view=co&pathrev=319707', ); }} This is necessary because of the pear project to github. The new file go-pear.phar does not include a web interface 3 make a directory that is not web-accessible eg {{PATH/pear}} 4 put the modified {{go-pear.php}} in your web-accessible pages eg {{PATH/public_html}} and install pear in {{PATH/pear}} 5 copy index.php from {{PATH/pear}} to {{PATH/public_html}} and edit so that {{ $pear_dir = 'PATH/pear/PEAR' }} 6 navigate to that file and configure PEAR by adding channel pear.horde.org and installing the packages enumerated in the horde documentation: Crypt_Blowfish, Net_DNS2 and Services_Weather 7 install the package horde/horde_role 8 go to the configuration page of PEAR and edit the value of 'Base Horde directory' to eg /PATH/public_html/horde 9 install the package horde/horde 10 navigate to your horde directory 11 if it does not work, create {{public_html/horde/config/horde.local.php}} to contain {{ <?php ini_set('include_path', '.:PATH/pear/PEAR:CURRENT_INCLUDE_PATH'); }} 12 and there you go!
