Pear installation directories?

Hi, I've just installed PEAR (with the Web installer) to the following directories: 1. Installation prefix /usr/local/pear 2. Binaries directory $prefix/bin 3. PHP code directory ($php_dir) $prefix/lib/pear 4. Documentation base directory $php_dir/docs 5. Data base directory $php_dir/data 6. Tests base directory $php_dir/tests 7. PEAR Installer cache directory $php_dir/cache 8. Cache TimeToLive 300 9. Filename of WebFrontend $prefix/index.php 10. php.exe path, optional (CLI command tools) $prefix after the installation the installer said something about not being able to display a link to the web-frontend (that isn't a surprise since none of the installation directories is not anywhere near my apache www-root). When I went to check out what the installer had done I found several .php files under /usr/local/pear/lib/*. The main questions here are: 1)did I screw up the installation? 2)Where should the $php_dir point to (www-root???)? 3)Can I just reinstall it and delete the old installation (I'm new with UNIX too..)?
