Installing PEAR on Win2k / PHP 4.0.4pl1

I am trying install PEAR on a development server that is running Win2k / IIS and PHP 4.0.4pl. As there is no automatic installation script for Windows, this needs to be done manually. 1. I have renamed the "PEAR.php.in" to "PEAR.php", however I'm unsure as to how the following constants should be defined within this file: ... define('PHP_BINDIR', '@prefix@/bin'); define('PEAR_INSTALL_DIR', '@PEAR_INSTALLDIR@'); define('PEAR_EXTENSION_DIR', '@EXTENSION_DIR@'); ... My queries are as follows: --> "PHP_BINDIR" obviously refers to where php.exe resides -- "C:\php" in my case. --> Should "PEAR_INSTALL_DIR" be defined as "C:\php\pear" or something else? --> What should "PEAR_EXTENSION_DIR" be defined as? 2. Aside from also adding the pear directory to the INCLUDE_PATH in php.ini, can anyone else suggest what else do I need to do to get up-and-running with PEAR on Win2k? Any assistance will be appreciated. -jnf
