Jon,

Dropped the "helloWorld.zip" into "/usr/local/labkey/externalModules/" -> unzipped -> restarted tomcat, was able to add helloworld module as "<Select Web Part>". The only issue is that the "js" internal libraries are not working... Also firebug is not displaying any errors when using "internal" libraries.... Does it work for you?

Thanks,
Diego
