I can't find app_videoswicth

I already compiled the Appconference 2.0, the new plugins that allows multipoint videoconferece in Asterisk. My Asterisk version is 1.4.9 and a SO CentOS 5.0. Everything is fine but I can’t find the VideoSwicth application,
for example in the CLI:
asteriskPBX> help videoswicth
NOTHING happens :blush:
