Ardour 2.4 on leopard

Has anyone got Ardour 2.4 up and running using X11 in leopard? Everything was working fine on tiger (before the upgrade). I guess the X11 that ships with leopard is somewhat broken.

In short: what X11 version are you using to run Ardour 2.4 in leopard?

You need to upgrade using the releases from

What Apple giveth, Apple taketh away. They finally installed X11 by default when they released Leopard. But they installed a broken X11.

Remember that native (X11-free) versions are referenced in our OS X IRC channel.
