pearweb 1.0.0RC1 first try and problem

While I wanted to see how "pearweb" handle database building with package.xml version 2.0 <postinstallscipt> task, I run in trouble. STEP 1 : Installation with a local copy of downloaded package is OK: $ pear -c pear.ini install pearweb-1.0.0RC1.tgz STEP 2 : run postinstallscript $ pear -c pear.ini run-scripts pear/pearweb STEP 3 : I follow questions on screen : Including external post-installation script "C:\wamp\php4\pear\pearweb.php" - any errors are in this script Inclusion succeeded running post-install script "pearweb_postinstall->init()" init succeeded Update pearweb database? [y] : Your choices: Update pearweb database?: y These Choices OK? (use "abort" to halt) [yes] : Database driver [mysqli] : mysql Database User name [pear] : AND THEN I GOT : 'stty' n'est pas reconnu en tant que commande interne ou externe, un programme exécutable ou un fichier de commandes. STEP 4 : so I decide to stop script : Database password [pear] : ^CTerminer le programme de commandes (O/N) ? o As "stty" is a unix command, and I'm on a windows platform, I think there is a problem somewhere. But I don't know where ? Help are welcome Laurent
