[Squeakland] Unable to run plugin on OS X

[tblanchard at mac.com]

I've just downloaded the Squeakland plugin and installed it on OS X.  
When I go to the kids projects area and click on one I get either:

the plugin with a menu open saying "there are updates available - load 
them?" which is frozen (clicks/mouse not tracked)

or:

textified binary in the browser pane

Its the same on Camino and Safari

Anybody know why?
