Installation of a local PEAR copy on a shared host

hi, according to http://pear.php.net/manual/en/installation.shared.php you can setup pear locally over ssh with the following command: pear -s -c ~/.pearrc -d doc_dir=~/pear/docs -d ext_dir=~/pear/ext \

       -d php_dir=~/pear/lib -d data_dir=~/pear/data -d test_dir=~/pear/tests \
       -d cache_dir=~/pear/cache -d bin_dir=~/pear/bin

although it does create the .pearrc with the correct values, it does not create the directory structure... As i understand it, it should create a directory ~/pear/ and fill it with the basic setup Am i missing something...? Any help would appreciated... Bas
