php compilation

Hello,
I was trying to install Ogg/vorbis pecl extension in wamp, but it seems to
be impossible.
So npw I'm trying to compile PHP on my PC forwarding
http://wiki.php.net/internals/windows/stepbystepbuild
but at 14th step I have an wire error : Erreur en entr=C3=A9e: Il n'y a pas=
 de
moteur de script pour l'extension de fichier ".js".
in english that make some thing like : Input error: there's no script motor
for ".js" file extension
I think I have installed all I need, cscript command is found so I don't
hunderstand where is the problem, if you have an idea you realy are welcome=
.

p.s.: It 's my first mail on this miling-list, maybe I should ask
php-installation mailing-list ?
